Sample run: 1) 0 612 18 24 30 2) Write a program segment using WHILE loop condition that writes the numbers 50 to 0 with a decrement of 10. Sample run: 50 40 30 20 100 3) Write a program segment using WHILE loop condition that reads a number from the user and writes the series of numbers starting from 0 to that number. The input/output should be the following (note the user input is in bold). HINT: You will need a count variable. Please enter a number:8 012345678 Write a program segment using WHILE loop condition that reads a number from user and writes the series of numbers starting from that number until zero with the folowing text. Also, outputs the sum of those numbers. The input/output should be the following (note the user input is in bold): 4) Please enter a number: 6 The positive numbers are: 6543210 The sum of the above numbers is: 21
