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 sc = new Scanner(System.in);
        while (true) {
            int h = Integer.parseInt(sc.next()); 
            int w = Integer.parseInt(sc.next());
            if (h == 0 && w == 0) {
                break;
            } else {
                for (int j = 0; j < h; j++) {
                    for (int i = 0; i < w; i++) {
                        System.out.print("#");
                    }
                    System.out.println();
                }
                System.out.println();
            }
