Your program:

package com.company;

class Main {

   public static void main (String[] args) {

       for( int i=5; i>0;i--)

       {

           for( int j=1; j<=i;j++)

           {

               System.out.print(j);

           }

           System.out.println();

       }

Solution:

Here comes the códe.

public class Pattern {

 public static void main(String[] args) {

    int i, j;

    for(i=5;i>=1;i--)  {

       for(j=1;j<=i;j++)

         System.out.print(j+" ");

       System.out.println();

    }

 }

}

Dry Run:

• When i = 5, inner loop displays numbers from 1 to 5.
• When i = 4, inner loop displays numbers from 1 to 4
• When i = 3, inner loop displays numbers from 1 to 3 and so on. In this way, the program works.
