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

Solution in JAVA (judge verdict: WA: Presentation Error)

import java.util.Scanner;
public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while (true) {
			int x = sc.nextInt();
			int y = sc.nextInt();
			if (x == 0 && y == 0)
				break;
			else
				opi(x, y);
		}
		sc.close();
	}

	static void opi(int x, int y) {
		for (int i = 0; i < x; i++) {
			for (int j = 0; j < y; j++) {
				System.out.print("#");
			}
			System.out.println();
		}
	}
