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.Scanner;

public class Main {

	public static void main (String[] args) {

		Scanner sc = new Scanner(System.in);
		ArrayList<Integer> h = new ArrayList<Integer>();
		ArrayList<Integer> w = new ArrayList<Integer>();

		int a, b;

		while ((a = sc.nextInt()) != 0 | (b = sc.nextInt()) != 0) {
			h.add(a);
			w.add(b);
		}

		for(int i = 0; i < h.size(); i++) {

			for(int j = 0; j < h.get(i); j++) {

				for(int k = 0; k < w.get(i); k++){

					System.out.print("#");

				}
				System.out.println();

			}
			System.out.println();

		}

	}
