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

Sample Input

3 4
5 6
2 2
0 0

Solution in JAVA (judge verdict: Runtime Error)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner stdin = new Scanner(System.in);
		int arr[][] = new int[4][2];
		int i = 0, j = 0, k = 0, count = 0;
		for (i = 0; i < 300; i++) {
			arr[i][0] = stdin.nextInt();
			arr[i][1] = stdin.nextInt();
			if (arr[i][0] == 0 && arr[i][1] == 0) {
				count = i;
				break;
			}
		}

		for (int test = 0; test < count; test++) {
			int row = arr[test][0];
			int col = arr[test][1];
			for (i = 0; i < row; i++) {
				for (j = 0; j < col; j++) {
					System.out.print("#");
				}
				System.out.println();
			}
			System.out.println();
		}
