nested for loops inverted half pyramid

Tags:



for a school project, I am trying to make an inverted half pyramid

my code is currently this

  public static void main(String[] args) {
            int rows = 5;
            for(int i = rows; i >= 1; --i) {
                for(int j = 1; j <= i; ++j) {
                    System.out.print(j + " ");
                }
                System.out.println();
            }
    }

with this output:

12345
1234
123
12
1

desired output:

 54321
 =4321
 ==321
 ===21
 ====1

Update (based on the updated requirement):

You need a loop to print the = equal to (rowsrow number) times.

public class Main {
    public static void main(String[] args) {
        int rows = 5;
        for (int i = rows; i >= 1; --i) {
            for (int j = i; j < rows; j++) {
                System.out.print("=");
            }
            for (int j = i; j >= 1; --j) {
                System.out.print(j);
            }
            System.out.println();
        }
    }
}

Output:

54321
=4321
==321
===21
====1

Original answer:

Your inner loop should be

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

i.e. for each row, it should start with the row number (i.e. i) and go down up to 1.
