Java for loop decrementing

can you guys pls help me

i want to code where the user will enter a number and then using for loop it will display the number in decrement for example:

Enter a number: 4

OUTPUT:
4
4-3
4-3-2
4-3-2-1
3
3-2
3-2-1
2
2-1
1-1

code it using for loop

this is my attempt code i’m getting confused:

  for (int i = num; i >= 1; i--) {
      for (int j = 1; j <= i; j++)
         {
               System.out.print(i+ "-" );
          for (int k = num; k>=i; k--)
             {
                System.out.print(k);
            }
            System.out.println();
        }

>Solution :

I can’t produce your last line(1-1) from the pattern with the below code, as if you think doesn’t match the pattern as well rather than that it can produce the exact same results:

    for (int x = n; x >= 1; x--) {
        for (int i = n; i >= 1; i--) {
            for (int j = n; j >= i; j--) {
                System.out.print (j);
                if (j > i) {
                    System.out.print("-");
                }
            }
            System.out.println();
        }
        n--;
    }
