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: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		StringBuilder output = new StringBuilder();
		Scanner scan = new Scanner(System.in);
		while(true) {
			int H = scan.nextInt();
			int W = scan.nextInt();
		
			if (H == 0 && W == 0)
				break;
			
			for (int i = 0; i < H; i++) {
				for (int j = 0; j < W; j++) {
					output.append("#");
				}
				output.append('\n');
			}
			output.append('\n');
		}
		System.out.print(output);
	}
