Do Exercise 6.4 from your textbook using recursion and the is_divisible function from Section 6.4. Your program may assume that both arguments to is_power are positive integers. Note that the only positive integer that is a power of "1" is "1" itself. After writing your is_power function, include the following test cases in your script to exercise the function and print the results: print("is_power(10, 2) returns: ", is_power(10, 2)) print("is_power(27, 3) returns: ", is_power(27, 3)) print("is_power(1, 1) returns: ", is_power(1, 1)) print("is_power(10, 1) returns: ", is_power(10, 1)) print("is_power(3, 3) returns: ", is_power(3, 3))
Answers
Answer:
Here is the python method:
def is_power(n1, n2): # function that takes two positive integers n1 and n2 as arguments
if(not n1>0 and not n2>0): #if n1 and n2 are not positive integers
print("The number is not a positive integer so:") # print this message if n1 and n2 are negative
return None # returns none when value of n1 and n2 is negative.
elif n1 == n2: #first base case: if both the numbers are equal
return True #returns True if n1=n2
elif n2==1: #second base case: if the value of n2 is equal to 1
return False #returns False if n2==1
else: #recursive step
return is_divisible(n1, n2) and is_power(n1/n2, n2) #call divisible method and is_power method recursively to determine if the number is the power of another
Explanation:
Here is the complete program.
def is_divisible(a, b):
if a % b == 0:
return True
else:
return False
def is_power(n1, n2):
if(not n1>0 and not n2>0):
print("The number is not a positive integer so:")
return None
elif n1 == n2:
return True
elif n2==1:
return False
else:
return is_divisible(n1, n2) and is_power(n1/n2, n2)
print("is_power(10, 2) returns: ", is_power(10, 2))
print("is_power(27, 3) returns: ", is_power(27, 3))
print("is_power(1, 1) returns: ", is_power(1, 1))
print("is_power(10, 1) returns: ", is_power(10, 1))
print("is_power(3, 3) returns: ", is_power(3, 3))
print("is_power(-10, -1) returns: ", is_power(-10, -1))
The first method is is_divisible method that takes two numbers a and b as arguments. It checks whether a number a is completely divisible by number b. The % modulo operator is used to find the remainder of the division. If the remainder of the division is 0 it means that the number a is completely divisible by b otherwise it is not completely divisible. The method returns True if the result of a%b is 0 otherwise returns False.
The second method is is_power() that takes two numbers n1 and n2 as arguments. The if(not n1>0 and not n2>0) if statement checks if these numbers i.e. n1 and n2 are positive or not. If these numbers are not positive then the program prints the message: The number is not a positive integer so. After displaying this message the program returns None instead of True of False because of negative values of n1 and n2.
If the values of n1 and n2 are positive integers then the program checks its first base case: n1 == n2. Suppose the value of n1 = 1 and n2 =1 Then n1 is a power of n2 if both of them are equal. So this returns True if both n1 and n2 are equal.
Now the program checks its second base case n2 == 1. Lets say n1 is 10 and n2 is 1 Then the function returns False because there is no positive integer that is the power of 1 except 1 itself.
Now the recursive case return is_divisible(n1, n2) and is_power(n1/n2, n2) calls is_divisible() method and is_power method is called recursively in this statement. For example if n1 is 27 and n2 is 3 then this statement:
is_divisible(n1, n2) returns True because 27 is completely divisible by 3 i.e. 27 % 3 = 0
is_power(n1/n2,n2) is called. This method will be called recursively until the base condition is reached. You can see it has two arguments n1/n2 and n2. n1/n2 = 27/3 = 9 So this becomes is_power(9,3)
The base cases are checked. Now this else statement is again executed return is_divisible(n1, n2) and is_power(n1/n2, n2) as none of the above base cases is evaluated to true. when is_divisible() returns True as 9 is completely divisible by 3 i.e. 9%3 =0 and is_power returns (9/3,3) which is (3,3). So this becomes is_power(3,3)
Now as value of n1 becomes 3 and value of n2 becomes 3. So the first base case elif n1 == n2: condition now evaluates to true as 3=3. So it returns True. Hence the result of this statement print("is_power(10, 2) returns: ", is_power(10, 2)) is:
is_power(27, 3) returns: True
Following are the program to the given question:
Program Explanation:
Defining a method "is_divisible" that takes two variable "a,b" inside the parameter.Usinge the return keyword that modulas parameter value and checks its value equal to 0, and return its value.In the next step, another method "is_power" is declared that takes two parameter "a,b".Inside the method, a conditional statement is declared, in which three if block is used. Inside the two if block it checks "a, b" value that is "odd number" and return bool value that is "True, False".In the last, if block is used checks "is_power" method value, and use multiple print method to call and prints its value.Program:
def is_divisible(a, b):#defining a method is_divisible that takes two parameters
return a % b == 0#using return keyword that modulas parameter value and checks its value equal to 0
def is_power(a, b):#defining a method is_power that takes two parameters
if a == 1:#defining if block that checks a value equal to 1 or check odd number condition
return True#return value True
if b == 1:#defining if block that checks b value equal to 1 or check odd number condition
return False#return value False
if not is_divisible(a, b):#defining if block that check method is_divisible value
return False##return value False
return is_power(a/b, b)#using return keyword calls and return is_power method
print("is_power(10, 2) returns: ", is_power(10, 2))#using print method that calls is_power which accepts two parameter
print("is_power(27, 3) returns: ", is_power(27, 3))#using print method that calls is_power which accepts two parameter
print("is_power(1, 1) returns: ", is_power(1, 1))#using print method that calls is_power which accepts two parameter
print("is_power(10, 1) returns: ", is_power(10, 1))#using print method that calls is_power which accepts two parameter

One lap around a standard high-school running track is exactly 0.25 miles. Write the function miles_to_laps() that takes a number of miles as an argument and returns the number of laps. Complete the program to output the number of laps.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
1.5
the output is:
6.00
Ex: If the input is:
2.2
the output is:

Your program must define and call the following function:
def miles_to_laps(user_miles)
Answers
Answer:
The program in python is as follows:
def miles_to_laps(user_miles):
return (user_miles/0.25)
mile = float(input("Number of Miles: "))
print("Number of laps: ",end="")
print('{:.2f}'.format(miles_to_laps(mile)))
Explanation:
The first line defines the function miles_to_lap
def miles_to_laps(user_miles):
This line returns the equivalent number of laps
return (user_miles/0.25)
The main method starts here
This line prompts user for input
mile = float(input("Number of Miles: "))
This line prints the string "Number of laps", without the quotes
print("Number of laps: ",end="")
This prints the equivalent number of laps to two decimal places
print('{:.2f}'.format(miles_to_laps(mile)))
The program converts the number of miles enters by the user to an equivalent measure in laps is written in python 3 thus :
def miles_to_laps(miles):
#initialize the function which takes in a single parameter
return (miles/0.25)
mile_value= eval(input("Number of Miles: "))
#allows user to input a value representing distance in miles
print("Number of laps: ",end="")
#display Number o laps with cursor on th same line
print('{:.2f}'.format(miles_to_laps(mile_value)))
#pass user's vlaue to the function to Obtain the lap value.
A sample run of the program is attached.

Now, let's improve our steps() function to take one parameter
that represents the number of 'steps' to print. It should
then return a string that, when printed, shows output like
the following:

print(steps(6))
111
222
333
444
555
666
Specifically, it should start with 1, and show three of each
number from 1 to the inputted value, each on a separate
line. The first line should have no tabs in front, but each
subsequent line should have one more tab than the line
before it. You may assume that we will not call steps() with
a value greater than 9.
Hint: You'll want to use a loop, and you'll want to create
the string you're building before the loop starts, then add

Answers
Answer:
Following are the difference to this question can be defined as follows:
Explanation:
In terms of projections of information into a reduced dimension group, we can consider the dimension structure of PCA and SVD technologies. In cases of a change in the length, based on consolidation, there's also a unit with dimensions. When we consider that the days have been aggregated by days or the trade of a commodity can be aggregated to both the area of the dimension, accumulation can be seen with a variance of dimension.Dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with the use of PCA and SVD.
What is dimensionality?Dimensionality involves reducing features that have been written or identified or constructing less features from a pool of important features.
Principal components analysis(PCA) and Single value decomposition(SVD) is a form or analysis that can be used to reduce some character that are not important to an information and can also help to select important variables from among many variables.
Therefore, dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with PCA and SVD.

Answer:
The summary including its given problem is outlined in the following section on the interpretation.
Explanation:
That's not entirely feasible, since at least n similarities have to be made to order n quantities. Find the finest representation where the numbers of 1 to 10 have already been arranged.
⇒ 1 2 3 4 5 6 7 8 9 10
Let's say that we identify one figure as the key then compared it towards the numbers across the left. Whether the correct number is greater, therefore, left number, are doing nothing to switch the location elsewhere.
Because although the numbers have already been categorized 2 has always been compared to 1 which would be perfect, 3 becomes especially in comparison to 2 and so much more. This should essentially take 9 moves, or nearly O(n) moves.
If we switch that little bit already
⇒ 1 3 2 4 5 6 7 8 9 10
3 Is contrasted with 1. 2 will indeed be matched against 3 as well as 2. Since 2 has indeed been exchanged, it must, therefore, be matched with 1 as there might be a case whereby each number z exchanged is greater than the number Y as well as the quantity X < Y.
X = 1, Y = 3, and Z = 2.Only one adjustment expanded the steps which culminated in n+1.
It should be noted that it won't be possible because at least n similarities have to be made to order n quantities.
From the information given, it should be noted that it's not possible for the engineer to implement an algorithm that can sort n elements (e.g., numbers) in fewer than n steps.
This is because there are at least n similarities have to be made to order n quantities. In this case, the numbers of 1 to 10 have already been arranged. When a number is greater, it should be noted that the left number will do nothing to switch the location elsewhere.

Answers
Answer:
See below
Explanation:
In case of a homogeneous network, Skype is an example and OpenTable is an example of a heterogeneous network.
Homogeneous networks are easier to get started with since its all pre-integrated, and even the troubleshooting is more convenient if a problem arises. However, it then becomes a security concern if you choose to place all that power to a single vendor - known as ' monoculture'. One event can affect the entire network. On the other hand, a heterogeneous set up does not run this risk. Several different components are utilized which are not as vulnerable to security threats.
In conclusion, homogeneous networks cost more and heterogeneous networks are more secure.

Summary
In this graded assignment, you will write Python programs that use loops to implement various algorithms.
Learning Outcomes
In completing this assignment, you will:
• Gain more experience converting an algorithm expressed using flowchart to one implemented in a Python program.
• Write a Python program using loops
Description
In a previous assignment in this course, you were asked to draw a flowchart for an algorithm that finds the two smallest items in a list, and then another assignment asked you to convert that flowchart to pseudocode.
Here is a pseudocode implementation of that algorithm:
1. min1- list
2. min2 - list,
3. for each item in list
4. if item
5. then if min1
6. then min2
7. else mint
8. else if item
9. then min2
10. output: min1, min2 item item item
Now, implement the algorithm in Python so that it correctly sets the values of min1 and min2 which should hold the two smallest values in the list, though not necessarily in that order.
In the code below, we have provided a list called "list" and initialized min 1 and min2 to hold the first two elements. Write your code starting at line 5 (you can remove the comments starting at line 6, and may need more space than what is provided), and be sure that the values of min1 and min2 are correctly set before the code reaches the "return (min1, min2)" statement on line 11.
As in the previous assignment, we will be using the Coursera automatic grading utility to test your code once you submit this quiz for grading, and this requires it to be within a function. So be sure that all of the code after line 1 is indented, and that you do not have any code after the "return (min 1, min2)" statement.
Keep in mind that the goal here is to write a program that would find the two smallest values of any list, not just the one provided on line 2. That is, don't simply set min 1 and min2 to-2 and -5, which are the two smallest values, but rather write a program that implements the algorithm from the flowchart and correctly sets min1 and min2 before reaching the return (min1, min2)" statement.
As before, you can test your program by clicking the "Run" button to the right of the code to see the results of any "print" statements, such as the one on line 10 which prints min1 and min2 before ending the function. However, please be sure that you do not modify the last two lines of the code block
1. def test(): # do not change this line!
2. list = [4, 5, 1, 9, -2, 0, 3, -5] # do not change this line!
3. min1 = list[0]
4. min2 = list[1]
5.
6. #write your code here so that it sets
7. #min1 and min2 to the two smallest numbers
8. # be sure to indent your code!
9.
10. print(min1, min2)
11. return (min1, min2) # do not change this line!
12. # do not write any code below here
13.
14. test() # do not change this line!
15. # do not remove this line!
Hints: The Python code for this algorithm is very similar to the pseudocode! Just be sure you are using the correct syntax. As in previous activities, don't forget that you can use the "print" function to print out intermediate values as your code is performing operations so that you can see what is happening

Explanation:
A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.
For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.
Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.
The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
The script shiftRight performs the inverse operation.
Each script prints the resulting string.
An example of shiftLeft.py input and output is shown below:

Answers
Answer:
In several organizations, the operating system (OS) functions at the core of the personal computers in use and the servers. The OS ought to be secure from external threats to its stored data and other resources.
Explanation:
In this regard, Intrusion detection systems play a critical role in protecting the sensitive data, along with software firewalls. Hardware firewalls protect the hardware elements in the network (such as storage drivers etc), the IDS and as well as the IPS.

A cashier distributes change using the maximum number of five-dollar bills, followed by one-dollar bills. Write a single statement that assigns num_ones with the number of distributed one-dollar bills given amount_to_change. Hint: Use %. Sample output with input: 19 Change for $ 19 3 five dollar bill(s) and 4 one dollar bill(s)
Answers
Answer:
num_ones = amount_to_change % 5
Explanation:
It is given that the cashier has to change the money in the maximum number of 5 dollar bills and remaining as $1 bills.
We have to write a single statement of code to assign the value to variable num_ones to find the value of $1 bills given amount_to_change.
Let us solve this by taking example:
If amount_to_change = $19
Then total number of $5 bills that can be given is 3. And amount that can be given as $5 bills is [tex]\bold{3 \times 5 = \$15}[/tex]
So, the remaining amount i.e. $19 - $15 = $4 will be given as one dollar bills.
Out of these $19, 4 bills of $1 can be found using the Modulus (%) operator.
Modulus operator leaves the remainder i.e.
Output of p % q is the remainder when a number 'p' is divided by 'q'.
19 % 5 = 4
4 is the number of one dollar bills to be given.
So, single line of code for the number of one dollar bills can be written as:
num_ones = amount_to_change % 5
Let us try it for amount_to_change = $30
We know that 6 number of $5 bills can be used to change the amount of $30 and no one dollar bill required.
num_ones = 30 % 5 = 0 (because 30 is completely divisible by 5 so remainder is 0)
So, the correct statement is:
num_ones = amount_to_change % 5
NMCI is the name used for a large-scale effort to link Navy and Marine Corps computer systems on bases, boats, and in offices around the world.

Answer:
The answer is "Intranet".
Explanation:
The intranet becomes an information exchange computer network, in which the resources collaborate with OS and other computing infrastructure within the organization. It is usually done without access from third parties and primarily uses for analysis of the data.
Here, the NMCI links the computer network of navy and maritime bodies on the bases of both the boats and the regional offices, that's why we can say that it is the example of the Internet.

Rosseta Technologies, an information technology service provider to a company based out of Germany, allows its employees to work from home twice a month. Its major concern is the leakage of confidential data from the laptops or an employee making copies of sensitive files on his personal laptop. Which of the following would help the firm enforce access controls and storage guidelines on its laptops?
a. Anenterprise search software
b. A binary search tool
c. A perceptive software pack
d. A Domain search engine
Answers
Answer:
a. An enterprise search software.
Explanation:
In this scenario, Rosseta Technologies, an information technology service provider to a company based out of Germany, allows its employees to work from home twice a month. In order to prevent the leakage of confidential data from the laptops or an employee making copies of sensitive files on his personal laptop, Rosetta technologies should use an enterprise search software.
Enterprise search software is a computer application which is typically used to make relevant data from sources, such as a database, file system and intranet searchable to a specific or defined group of people.
An enterprise search software would help the firm enforce access controls and storage guidelines on its laptops.
On enterprise search software, there are basically two (2) ways to enforce access controls as a security policy on users;
1. Early binding: at the index stage, permissions are analyzed and ascribed to each document in the enterprise search software.
2. Late binding: it involves the process of analyzing permissions and ascribing them to each document at the query stage in the enterprise search software.
Create an application in Java that asks a user for a number of hours, days, weeks, and years. It then computes the equivalent number of minutes (ignoring leap years)
Answers
Answer:
The program written in Java is as follows;
The program takes input for hours, days, weeks and months;
Then the inputs are converted to minutes individually and then summed up
For you to better understand the program, made use of comments to explain difficult lines,
The program is as follows

System.out.print("Hours: ");
//This line accepts input for hours
hours = input.nextInt();
//This line prompts user for days input
System.out.print("Days: ");
//This line accepts input for days
days = input.nextInt();
//This line prompts user for weeks input
System.out.print("Weeks: ");
//This line accepts input for weeks
weeks = input.nextInt();
//This line prompts user for years input
System.out.print("Years: ");
//This line accepts input for years
years = input.nextInt();
//This line converts hours to minute
int minute = 60 * hours + 1440 * days + 10080 * weeks + 525600 * years;
//This line prints the equivalent minute of user input
System.out.println(minute +" minutes");
}

ou are sending a very small amount of information that you need the listening program to respond to immediately. Which Transmission Control Protocol (TCP) flag will be used
Answers
Answer:
The Push flag
Explanation:
When sending a very small amount of information which the listening program needs to respond to immediately. The Transmission Control Protocol (TCP) flag that will be used is the Push flag.
The Push flag, like the Urgent flag, was brought into existence to ensure that the data is given the priority it deserves and it is urgently processed at the sending or receiving end. Push flag is used more often at the beginning and end of a data transfer, it affect the way the data is handled at both ends (sending and receiving).
When developers make available new applications, they must always ensure they follow specific guidelines given by the RFC's to ensure that the applications created work properly / efficiently and control the flow of data in and out of the application layer of the OSI model perfectly. When used, the Push bit ensure that the data segment is handled correctly and given the deserved priority at both ends of a virtual connection.
