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

Solution in JAVA (judge verdict: Accepted)

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


public class Main {

	private static final int BIG_NUM  = 2000000000;

	public static void main(String[] args) {

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

		int H,W;

		String work[] = new String[2];

		while(true){

			try {
				work = br.readLine().split("[\\s]+");
				if(work[0].equals("0") && work[1].equals("0"))break;

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

				for(int row = 0; row < H; row++){
					for(int col = 0; col < W; col++){
						System.out.printf("#");
					}
					System.out.printf("\n");
				}

				System.out.printf("\n");

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