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: WA: Presentation Error)

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

public class Main {

	public static void main(String[] args) throws Exception {
		BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
		String s;
		int inCnt = 0;
		while ((s = stdIn.readLine()) != null) {
			inCnt++;
			String[] se = s.split(" ");
			int h = Integer.valueOf(se[0]);
			int w = Integer.valueOf(se[1]);
			if (h == 0 && w == 0)
				break;
			doMain(inCnt, h, w);
		}
		System.exit(0);
	}

	private static void doMain(int inCnt, int h, int w) {
		for (int i = 0; i < h; i++) {
			for (int j = 0; j < w; j++)
				System.out.print("#");
			System.out.println("");
		}
	}
