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 sc = new Scanner(System.in);
		int H;
		int W;
		int count;
		int[] detaH = new int[300];
		int[] detaW = new int[300];
		for (count = 0; true; count++) {
			H = sc.nextInt();
			W = sc.nextInt();
			if (H == 0 && W == 0) {
				break;
			}
			detaH[count] = H;
			detaW[count] = W;
		}
		for (int i = 0; i < count; i++) {
			for (int i2 = 0; i2 < detaH[i]; i2++) {
				for (int i3 = 0; i3 < detaW[i]; i3++) {
					System.out.print("#");
				}
				System.out.print("\n");
			}
			System.out.print("\n");
		}
		sc.close();
	}
