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.util.Scanner;

public class Main{
	public static void main(String[] args) {
		Scanner src = new Scanner(System.in);
		
		
		//H,Wが両方とも0になるまで繰り返す
		while(true) {
			
			
			//縦、横の高さ
			int H  = src.nextInt();
			int W  = src.nextInt();
			
	      //HW両方が0になった場合終了
	     if((W == 0) && (H == 0)) {
	    	 break;
	     }  
			
			//縦の列の繰り返し
	        for (int i = 1; i <= H; i++) {
	        	
	        	
	        	//横の列の繰り返し
	            for (int j = 1; j <= W; j++) {
	                System.out.print("#");
	            }
	            
	            //縦に１列進む
	            System.out.println();
			}
	        
	        System.out.println();
	        

		}
	}
