Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        while (true) {
            int H = scan.nextInt(), W = scan.nextInt();
            if (H == 0 && W == 0) {
                break;
            }

            for (int h = 0; h < H; h++) {
                for (int w = 0; w < W; w++) {
                    System.out.print("#");
                }
                System.out.println();
            }
            System.out.println();

        }
    }
