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) throws Exception {
        Scanner input = new Scanner(System.in);
        while(true){
        int h = input.nextInt();
        int w = input.nextInt();
        if(h==0&&w==0){
            break;
        }
        for(int n = 0; n < h; n++){
        for(int i = 0; i < w; i++){
            System.out.print("#");
        }
        System.out.println();
        }
        System.out.println();
        }
    }
