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) {
		Scanner sc = new Scanner(System.in);
		int H = 0;
		int W = 0;
		String sh = "#";
		while(true) {
			H = sc.nextInt();
			W = sc.nextInt();
			if(H == 0 && W ==0)break;
			for(int i = 0; i < H; i++) {
				for(int j = 0; j < W; j++) {
					System.out.print(sh);
				}
				System.out.println("");
			}
			System.out.println("");
		}
		sc.close();
	}
