Answer:

10 9 8 7 6 5 4 3 2 1

Explanation:

Input: N = 20 

Output: 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1

Run a loop from 20 to 1 and print the value 20 for each iteration. Decrement the value of 20 by 1 after each iteration.

Below is the implementation of the above approach. 

for example ,

Given a number N, the task is to print the numbers from N to 1.

Input: N = 10 

Output: 10 9 8 7 6 5 4 3 2 1

Run a loop from N to 1 and print the value of N for each iteration. Decrement the value of N by 1 after each iteration.

Answer:

Software Used:

  • Python

Required program:

for i in range (20,0,-1):

   print(i)

Explanation:

In this program we have set initial value to 20, final values to 0 and step value to -1. We have set initial value to 20 and final value to 0 as we want our program to print the numbers 20-1 in reverse order. We have set step value to  -1 as we want our numbers in the range decrease from 20 to 1. We haven't set final value to 1 as final value takes the value of 1 number less if the range is increasing, and it takes value of 1 number more if the range is decreasing. (i.e. If we want 20 as a final value we will write the final value in the program as 21.)

Output:

The output of the following program will be as follows:

20

19

18

17

16

15

14

13

12

11

10
