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{
		int h,w;
		String[] str;

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

		while(true){
			str = br.readLine().split(" ");
			h = Integer.parseInt(str[0]);
			w = Integer.parseInt(str[1]);

			if(h==0 && w==0)break;

			for(int i = 0; i < h; i++){
				for(int j = 0; j < w; j++){
					builder.append("#");
				}
				builder.append("\n");
			}
			builder.append("\n");
		}
		builder.delete(builder.length() - 1, builder.length());

		System.out.println(builder.toString());
		br.close();
	}
}
