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

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		List<Integer> height = new ArrayList<>();
		List<Integer> width = new ArrayList<>();
		int h = 0;
		int w = 0;


		int count = 0;
		boolean judge = false;
		while(!judge){
			h = sc.nextInt();
			w = (sc.nextInt());

			if(h == 0 && w == 0){
				judge = true;
			}else{
				height.add(h);
				width.add(w);
				count++;
			}
		}
		for(int i = 0; i < count; i++){
			for(int j = 0; j < height.get(i); j++){
				for(int k = 0; k < width.get(i); k++){
					System.out.print("#");
				}
				System.out.println();
			}
			System.out.println();
		}


	}
