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

		String str;
		String[] arrStr;
		StringBuilder sb = new StringBuilder();
		try {

			final String sharp = "#";

			while (true) {
				str = br.readLine();
				arrStr = str.split(" ");

				int h = Integer.parseInt(arrStr[0]);
				int w = Integer.parseInt(arrStr[1]);
				if(h == 0 && w == 0){
					break;
				}
				for (int i = 0; i<h; i++) {
					for (int j = 0; j < w; j++) {
						sb.append(sharp);
					}
					sb.append("\n");
				}
				System.out.println(sb.toString());
				sb.setLength(0);
			}

		} catch (IOException e) {
			e.printStackTrace();
		}
	}
