Part One: Get Valid Input Read in two integers from the user: a lower end of a range and an upper end of a range. Check if the numbers are valid (lower cannot be greater than upper). If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Part Two: Calculate the Sum Use a loop to calculate the sum of all values from lower (inclusive) to upper (inclusive). Output the sum to the user. Part Three: Analyze the Sum Determine if the sum is even or odd. Determine if the sum is positive, negative, or zero. Output this information to the user.

Input Notes:Both the current time and the waiting time are entered in the form HH:MM where HH and MM are integers signifying hours and minutes respectively. In response to the continuation prompts (described below) the user types a y or a Y to signify "continue" with any other character signifying "quit". Output Notes (Prompts and Labels):At the outset the program prints the title "Compute completion time from current time and waiting period". The program then prompts for the current time with the prompt "Current time:" followed by the instructions "Enter 24 hour time in the format HH:MM". After…arrow_forward
- Guessing Numbers---The problem is to guess what number a computer has in mind. You will write a program that randomly generatesan integer between 0 and 100, inclusive. The program prompts the user to enter a number continuously until the number matches the randomly generated number. For each user input, the program tells the user whetherthe input is too low or too high, so the user can make the next guess intelligently. Here is a sample run .

Once "done" is entered, print out the max, min, and average of the height numbers. Correct height data should be number between 50cm and 250cm. If the user enters number out of the range, or anything other than a number, detect the mistake and print an error message and skip to the next number. Sample input and output: Enter a height: 300 Invalid input Enter a height: 10 Invalid input Enter a height: 200 Enter a height: good Invalid input Enter a height: 180 Enter a height: 165 Enter a height: done Max: 200.0 Min: 165.0 Average: 181.67arrow_forwardLoops (Beating them to death)I.
