Inverted Number Triangle

DEMO-C-32 • Programming in C

Browser-only practice

Problem Statement

Write a program that reads an integer N and prints an inverted triangle made of numbers.

The pattern should look like this:

  • The first line contains numbers from 1 to N, separated by spaces.
  • The second line contains numbers from 1 to N-1.
  • This continues until the last line, which contains only 1.

Use nested loops to generate the pattern.

Constraints

You must use nested loops to solve this problem.

Input Format

A single integer N where 1 <= N <= 20.

Output Format

Print the inverted triangle of numbers as described above. Each row should have numbers separated by spaces, and each row ends with a newline character.
