Define a function in Scheme (or relation in Prolog) that checks whether a set of elements (represented as a list) is a subset of another set (represented as a list).
Answer:
subset([],[]).
subset([X|L],[X|S]) :-
subset(L,S).
subset(L, [_|S]) :-
subset(L,S).
Success:
subset([1,3], [1,2,3]).
subset(X, [1,3,4]). % error handling to compare sets in a given order
Fail:
subset([2,1], [1,2,3]). % compares in a different order from the first.
Explanation:
The function "Subset" in the source code above accepts two sets, then checks if the first set is a subset of the second. The code returns true if the condition is met.

When two well-informed people have different perspectives on a problem, it is often because they are focusing on a different approach to the problem, not that one side is right and the other is wrong.
a
False
b
True
Answer:
B. True.
Explanation:
The problem-solving process can be defined as the systematic approach used to identify and determine the solution to a particular problem.
The steps involved in the problem-solving process are;
1. Identify and define the problem: this is the first step to be taken in solving a problem. This is to ensure that, the focus is on the main issue or situation and all efforts is channeled in the right direction rather than the symptoms.
2. Gathering of information: this helps to consider the options available in solving a problem effectively.
3. Consider your options: this helps to compare the available and viable solutions to the problem.
4. Weigh disadvantages and evaluate a solution: you weigh the disadvantages of each solution, before choosing the one with the least disadvantages.
When two well-informed people have different perspectives on a problem, it is often because they are focusing on a different approach to the problem, not that one side is right and the other is wrong. Considering the fact that, all humans and intellectuals have different perspectives on a problem, the technique or approach that would be adopted by them to proffer a solution to the problem is most likely to differ. Thus, it's possible to have more than one approach to proffer a solution to the same problem.

Describe how you would create a Java program that prompted the user to correctly enter a username and password. The username is not case sensitive, bu
Answer:
Explanation:
The program in question would create a new Scanner Object which asks the user for the Username first. It would then save this input into a temporary variable and compare it to the actual username in the database. Since the username is not case sensitive, we would use the toLowerCase() method on both the input and the database username so that they match even if the letters are not the same case structure. If both usernames match then we would move on to ask the user for the Password and compare it with the database password for that user. Since this one is case sensitive we would compare as is. Finally, if both Username and Password match we would print "Hello World" otherwise we would print "Login Failed."

Using a while loop, create an algorithm extractDigits that prints the
individual digits of a positive integer.
For instance, extractDigits(54321); would create the output:
1
2
3
4
5
Hint: The % and the / operators are going to be very useful in this program.
How can you use these to extract the last digit of the glven number?
Answer:
Follows are the code to this question:
#include <stdio.h>//defining header file
void extractDigits (int n)//defining a method extractDigits that holds
{
int x;//defining integer variable
while (n > 0)//defining while loop for check value is greater than 0
{
x = n % 10;//holding remainder value
n = n / 10;// holding quotient value
printf("%d\n", x);//print remainder value
}
}
int main ()//defining main method
{
extractDigits (54321);//calling above method by passing integer value
}
Output:
1
2
3
4
5
Explanation:
In the above-given code a method "extractDigits" is defined that accepts an integer parameter, and inside the method an integer variable is declared, that use while loop to check value is greater than 0, and calculate the individual digits, and print its values, and inside the main method we call the above method.

A structure, in C, has been given by: struct MYSTRUCT { char buf[15] shorts S int i; } * Select the proper keywords in the proper order) needed to declare, in C, an array of 8 structures (called MYSTR) of type MYSTRUCT. * Choose the following the expression for accessing Element 4 (i.e., index 4) of the char array (BUF) in the third element (i.e., index 3) of MYSTR. * Choose the statement to declare, in C, a pointer called MYSPTR that points to a structure of type MYSTRUCT. * Select the proper method to access the short, S, in a structure pointed to by MYSPTR by de-referencing the pointer.*Select the proper method to access the short, S, in a structure pointed to by MYSPTR by using the shorthand notation.
Answer:
MYSTRUCT myStruct[8]; // statemnt to create an array of struct variables
myStruct[3].buf[4] // statement to access the fourth element of the array of the struct variables.
struct * MYSPTR = &myStruct; // This statement creates a pointer.
To dereference and access the S variable of the struct data structure in the array;
(*MYSPTR).S and its shorthand notation MYSPTR -> S
Explanation:
A structure is a data structure in C language that is used to hold descriptive data of an object. The keyword struct is used to create the structure. An array of struct holds instances of a struct variable, where each struct can be accessed using the regular array indexing and the variables of the structs in the array can be accessed using dot notation.
1. Hypothesis: It is easier to establish an ethical work environment in a non-profit organization than in a for-profit organization. Provide three facts or opinions that support this hypothesis. Provide three facts or opinions that refute the hypothesis.
Answer:
Explanation:
Nonprofit organizations may have more possibilities to remain ethical because their work is not aimed at capital, but at the welfare of something or some situation.
When money is not involved in organizations, things become more honest and simple.
Usually people involved in nonprofit organizations have a different worldview and want to change reality.
In a non-profit organization, a social good is sought, as opposed to an organization that aims at money, but there are people who only use non-profit organizations as status.
Even though the environment aiming at a change in reality can become a work without ethics and that breaks the social rules.
What makes people truly ethical are people, a for-profit organization can be a more ethical environment than a non-profit organization.

Which of the following are cache replacement algorithms.
a. Thrashing
b. LILO
c. LRU
d. FIFO
e. Random
f. Double elimination
Answer:
FIFO,LRU,Random are the cache replacement algorithms.
Explanation:
FIFO we use for cache replacement as the first enter the cache first is evicted without ant regard of how many times it was before accessed.
LRU (Least recently used ) it is a important cache replacement algorithm As it arranges the items in order of use and it will allow you to identify quickly which item hasn't been used for the longest amount of time.
Random is also used but it is used very less As it will select any of the data item from cache and replaces with the desire one And it will not keep track of history
python Which data type is the best choice to store the number of wins associated with each basketball team in the NBA
Information with numerical values is represented using Python's numeric data types. A number can be made up of integer, floating-point, or even complex values.
What data type of Python best choice to store the number?You must declare a variable in some programming languages before using it or specify the data that will be stored in it, such as a number.
When an integer value is passed to the IntToStr method, a string containing the value's decimal representation is produced.
The output string is always decimal, even though integer values can be decimal, octal, or hexadecimal. Use the FloatToStr method or the Format method to convert floating-point numbers.
Therefore, These values are classified by Python as being members of the int, float, and complex classes. Integers—This value is represented by the int class.
