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: WA: Presentation Error)

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();
			int w = scan.nextInt();

			if (1 <= h && h <= 300 && 1 <= w && w <= 300) {
				for (int i = 0; i < h; i++) {
					for (int j = 0; j < w; j++) {
						System.out.print("#");
					}
					System.out.println("");
				}
			} else if (h == 0 && w == 0) {
				break;
			}
		}
