Python Programming:
Write a program using unittest.TestCase methods to confirm that the addition and subtraction of date and timedelta objects produce correct results.
Important notes:
Use the unittest module to create a TestCase to test that the addition and subtraction of date and timedelta objects produce correct results... For example I could create a TestCase with a function that tests the addition of date and timedelta objects; a function that tests the subtraction of date and timedelta and then call unittest's main method at the end.
When you run this program, it should tell us whether the text was successful or not. See attached image for what the output should look like.

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

- 2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not.

Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part.

- (language: Intellij-Java) Part One: Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5). Part2: Write a method which gets a value from the user and convert that value from Celsius to Fahrenheit: - For Celsius to Fahrenheit conversion use: F = 9*C/5 + 32 - Print the result of the conversion Part3: Create a method which takes an integer array input from the user and reverses the elements in the array. Print the reversed array. - For example, the expected “reversed” result for an array [5,33,0,8,2] is [2,8,0,33,5] - Don't use any inbuilt/existing array reverse method.
