Program Plan Intro
Factorial
Program plan:
- Import the necessary package.
- Create a class “Factorial1” ,
- Define the function “main()”,
- Declare and initialize the necessary variables.
- Create “Scanner” object to get the user input.
- Get the user input using “next()”.
- Execute “while” to check whether the entered input is negative.
- If t is a negative input, then ask the user for the next non-negative input.
- Check whether the value of “n” is “0”,
- Print the factorial value as “1” for “0”.
- Otherwise, check whether the value of “” is greater than or equal to “1”,
- If it “true”, execute the next statement inside “do”.
- Calculate the factorial.
- Increment the counter variable.
-
- Check the condition at the end of “do-while” statement.

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?

- 4. Odd-Even-inator by CodeChum Admin My friends are geeking out with this new device I invented. It checks if a number is even or odd! ? Do you want to try it out? Instructions: In the code editor, you are provided with a function that checks whether a number is even or odd. Your task is to ask the user for the number of integer, n, they want to input and then the actual n number values. For each of the number, check whether it is even or odd using the function provided for you. Make sure to print the correct, required message. Input 1. Integer n 2.

- 1) Simple Calculator: In Python, implement a simple calculator that does the following operations: summation, subtraction, multiplication, division, sqrt, power, natural log and abs. a) Follow the instructions below: To work with the calculator, the user is asked to enter the first number, then the operation, and finally, a second number if required. Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forward5.
