Answer 2

Answer:

public class Main{

public static void main(String[] args){

       for (int i = 1; i <= 5; i++){

           for(int j = i; j >= 1; j--){

               System.out.print(j + " ");

           }

           System.out.println();

       }

   }

}

Explanation:

Run two different loops for Row and column and print the value of j.

First loop will run in increasing order till 5(or till whatever row you want, it can 7 or 8 or 10 or anything) and 2nd will run in decreasing order till 1.
