Write a program that calculates the area & perimeter of a rectangle, where
the values for width and length are given by the users.

what is volitile memory?

In this exercise we will practice using loops to handle collections/containers. Your job is to write a program that asks the user to enter a sentence, then it counts and displays the occurrence of each letter.
Note: your program should count the letters without regard to case. For example, A and a are counted as the same.
Here is a sample run:
Enter a sentence: It's a very nice day today!
a: 3 times
c: 1 times
d: 2 times
e: 2 times
i: 2 times
n: 1 times
o: 1 times
r: 1 times
s: 1 times
t: 2 times
v: 1 times
y: 3 times
Notes:
The purpose of this problem is to practice using loops and collections/containers/strings.
Please make sure to submit a well-written program. Good identifier names, useful comments, and spacing will be some of the criteria that will be used when grading this assignment.
This assignment can be and must be solved using only the materials that have been discussed in class: loops, the index system, strings, lists and/or dictionaries. Do not look for or use alternative methods that have not been covered as part of this course.
How your program will be graded:
correctness: the program performs calculations correctly: 40%
complies with requirements (it properly uses loops, and containers/strings): 40%
code style: good variable names, comments, proper indentation and spacing : 20%
Language is python 3

use a for loop to create a random forest model for each value of n estimators from 1 to 30;
• evaluate each model on both the training and validation sets using MAE;
• visualize the results by creating a plot of n estimators vs MAE for both the training and validation sets
After that you should answer the following questions:
• Which value of n estimators gives the best results?
• Explain how you decided that this value for n estimators gave the best results:
Why is the plot you created above not smooth?
• Was the result here better than the result of Part 1? Wha: % better or worse was it? in python

What is the function for displaying differences between two or more scenarios side by side?
Macros
Merge
Scenario Manager
Scenario Summary

In a program, write a method that accepts two arguments: an array of integers and a number n. The method should print all of the numbers in the array that are greater than the number n (in the order that they appear in the array, each on their own line).
In the same file, create a main method and call your function using the following data sets:
The array {1, 5, 10, 2, 4, -3, 6} and the number 3.
The array {10, 12, 15, 24} and the number 12.
My code:
public class LargerThanN
{
public static void print(int[] array,int n)
{
for(int i=0; i {
if (array[i]>n)
System.out.println(array[i]);
}
System.out.println();
}
public static void main(String[] args)
{
int[] array1 = {1,5,10,2,4,-3,6};
int num1=3;
print(array1,num1);
int[] array2 = {10, 12, 15, 24};
int num2 = 12;
print(array2, num2);
}
}

Write a python 3 function named words_in_both that takes two strings as parameters and returns a set of only those words that appear in both strings. You can assume all characters are letters or spaces. Capitalization shouldn't matter: "to", "To", "tO", and "TO" should all count as the same word. The words in the set should be all lower-case. For example, if one string contains "To", and the other string contains "TO", then the set should contain "to".
1.Use python's set intersection operator in your code.
2.Use Python's split() function, which breaks up a string into a list of strings. For example:

sentence = 'Not the comfy chair!'
print(sentence.split())
['Not', 'the', 'comfy', 'chair!']
Here's one simple example of how words_in_both() might be used:

common_words = words_in_both("She is a jack of all trades", 'Jack was tallest of all')

In the computing environment the numerical value represented by the pre-fixes kilo-, mega-, giga-, and so on can vary depending on whether they are describing bytes of main memory or bits of data transmission speed. Research the actual value (the number of bytes) in a Megabyte (MB) and then compare that value to the number of bits in a Megabit (Mb). Are they the same or different

1. Write a class Name that stores a person’s first, middle, and last names and provides the following methods:
public Name(String first, String middle, String last)—constructor. The name should be stored in the case given; don’t convert to all upper or lower case.
public String getFirst()—returns the first name
public String getMiddle()—returns the middle name
public String getLast()—returns the last name
public String firstMiddleLast()—returns a string containing the person’s full name in order, e.g., "Mary Jane Smith".
public String lastFirstMiddle()—returns a string containing the person’s full name with the last name first followed by a comma, e.g., "Smith, Mary Jane".
public boolean equals(Name otherName)—returns true if this name is the same as otherName. Comparisons should not be case sensitive. (Hint: There is a String method equalsIgnoreCase that is just like the String method equals except it does not consider case in doing its comparison.)
public String initials()—returns the person’s initials (a 3-character string). The initials should be all in upper case, regardless of what case the name was entered in. (Hint: Instead of using charAt, use the substring method of String to get a string containing only the first letter—then you can upcase this one-letter string. See Figure 3.1 in the text for a description of the substring method.)
public int length()—returns the total number of characters in the full name, not including spaces.
2. Now write a program TestNames.java that prompts for and reads in two names from the user (you’ll need first, middle, and last for each), creates a Name object for each, and uses the methods of the Name class to do the following:
a. For each name, print
first-middle-last version
last-first-middle version
initials
length
b. Tell whether or not the names are the same.
Here is my code. I keep getting a method error with getFullName in the Name.java file. Please help me re-write the code to fix this issue.
//Name.java
public class Name
{
private String firstName, middleName, lastName, fullName;
public Name(String first, String middle, String last)
{
firstName = first;
middleName = middle;
lastName = last;
String fullName = firstName '+' middleName '+' lastName;
}
public String getFirst()
{
return firstName;
}
public String getMiddle()
{
return middleName;
}
public String getLast()
{
return lastName;
}
public String firstMiddleLast()
{
return firstName + ' ' + middleName + ' ' + lastName;
}
public String lastFirstMiddle()
{
return lastName + ", " + firstName + ' ' + middleName;
}
public boolean equals(Name otherName)
{
return fullName.equalsIgnoreCase(otherName.getFullName());
}
public String initials()
{
return firstName.toUpperCase().substring(0,1)
+ middleName.toUpperCase().substring(0,1)
+ lastName.toUpperCase().substring(0,1);
}
public int length()
{
return firstName.length() + middleName.length() + lastName.length();
}
}
//NameTester.java
import java.util.Scanner;
public class NameTester

public static void main(String[] args)

String middleName1 = new String();
String lastName1 = new String();
String firstName2 = new String();
String middleName2 = new String();
String lastName2 = new String();
System.out.print("\nPlease enter a first name: ");
firstName1 = input.nextLine();
System.out.print("Please enter a middle name: ");
middleName1 = input.nextLine();
System.out.print("Please enter a last name: ");
lastName1 = input.nextLine();
Name name1 = new Name(firstName1, middleName1, lastName1);
System.out.print("\nPlease enter another first name: ");
firstName2 = input.nextLine();
System.out.print("Please enter another middle name: ");
middleName2 = input.nextLine();
System.out.print("Please enter another last name: ");
lastName2 = input.nextLine();
Name name2 = new Name(firstName2, middleName2, lastName2);
System.out.println();
System.out.println(name1.firstMiddleLast());
System.out.println(name2.firstMiddleLast());
