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);

    while(true){
        int H = sc.nextInt();
        int W = sc.nextInt();
        if(H==0 && W == 0){
            break;
        }
        for(int y=0; y<H; y++){
            for(int x=0; x<W; x++){
                System.out.print("#");
            }
            System.out.println();
        }   
        System.out.println();
    }
 }
