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 {
	static int height = 0;
	static int weight = 0;

	public static void main(String[] args) throws Exception {
		// TODO ?????????????????????????????????????????????
		boolean zeroFlag = true;
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String line = br.readLine();

		while (zeroFlag) {
			String[] nyuryokuStr = line.split("[\\s]+");
			height = Integer.parseInt(nyuryokuStr[0]);
			weight = Integer.parseInt(nyuryokuStr[1]);
			if (height == 0 && weight == 0) {
				zeroFlag = false;
			} else {
				for (int h = 0; h < height; h++) {
					for (int w = 0; w < weight; w++) {
						if (w == weight - 1) {
							System.out.print("#");
							System.out.println("");
						} else {
							System.out.print("#");
						}
					}
				}
				line = br.readLine();
			}
		}
	}
