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{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		int a = 0;
		int b = 0;

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

			a = Integer.parseInt(s[0]);
			b = Integer.parseInt(s[1]);
			if((a <= 300) &&(b <= 300)){
				if((a == 0)&&(b == 0)){
					break;
				}

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