Write a Java program to display the pattern like a right angle triangle with a number.

Test Data
Input number of rows : 10

Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise16 {

   public static void main(String[] args)

{
   int i,j,n;
   System.out.print("Input number of rows : ");
 Scanner in = new Scanner(System.in);
		    n = in.nextInt();

   for(i=1;i<=n;i++)
   {
	for(j=1;j<=i;j++)
	  System.out.print(j);

    System.out.println("");
    }
}
}

Sample Output:

Input number of rows : 10
