Write a program that will add up the series of numbers: 99, 98, 97… 3, 2, 1. The program should print the running total as well as the total at the end. The program should use one for loop, the range() function and one print() command.

The program that will add up the series of numbers: 99, 98, 97… 3, 2, 1 is represented as follows using for loop, the range() function and one print() function.

sum = 0

for i in range(1, 100):

   sum += i

print(sum)

The code is written in python.

The variable sum is initialise to zero.

For loop is used to loop through the range of number 1 to 100(excluding 100).

Then the numbers are added to the sum initialised to zero.

The total sum is then printed.

isum = 0

for i in range(99,0,-1):

   isum = isum + i

print(isum)

Explanation:

This line initializes isum to 0

isum = 0

The following iteration starts from 99 and ends at 1

for i in range(99,0,-1):

This line adds the series

   isum = isum + i

This line prints the sum of the series

print(isum)
