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.util.*;

class Main{
	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
		int[] h = new int[300], w = new int[300];
		int cnt = 0;
		
		while(true){
			h[cnt] = sc.nextInt();
			w[cnt] = sc.nextInt();
			
			if(h[cnt] == 0 && w[cnt] == 0)
				break;
			
			cnt ++;
		}
		
		for(int i = 0; i < cnt; i++){
			for(int j = 0; j < h[i]; j++){
				for(int k = 0; k < w[i]; k++){
					System.out.print("#");
				}
				System.out.println("");
			}
			System.out.println("");
		}
	}
