Question

Challenging Numerical Triangles

by CodeChum Admin

You probably have encountered Triangle pattern problems before when you started learning programming. Let’s see how well you do with numbers this time. Try to look at the examples closely and think of an algorithm that replicates the outputs. Go for it!

Input

A single line containing an integer n.

9

Output

The output generated based on the inputted integer n.

1

23

456

Answer 1

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int line = 1;
        int counter = line;
        for (int i = 1; i <= n; i++) {
            System.out.print(i);
            if (--counter == 0) {
                counter = ++line;
                System.out.println();
            }
        }
    }
}
