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: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {

	public static void main(String[] args) throws IOException {

		int H = 0;
		int W = 0;

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

		while (true) {
			String str = br.readLine();
			String[] num = str.split(" ");

			H = Integer.parseInt(num[0]);
			W = Integer.parseInt(num[1]);

			if (H == 0 && W == 0) {
				break;
			}
			for (int i = 0; i < H; i++) {

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