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: Wrong Answer)

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		List<Integer> w = new ArrayList<Integer>();
		List<Integer> h = new ArrayList<Integer>();


		 for(int i=0;;i++){
			 w.add(i, scan.nextInt());
			 h.add(i, scan.nextInt());
			 if(w.get(i)==0 && h.get(i)==0) break;
		 }

		 for(int i=0;;i++){
			if(w.get(i)==0 && h.get(i)==0) break;
			 printSquare(w.get(i),h.get(i));

		 }
	}

	static void printSquare(int w,int h){
		for(int i=0 ;i< h;i++){
			for(int j=0; j < w;j++){
				System.out.print("#");
			}
				System.out.println();
		}
			System.out.println();
	}
