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

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws Exception {
        Scanner sc = new Scanner(System.in);
        
        int H;
        int W;
        int x;
        int y;
        
        while(true){
            H = sc.nextInt();
            W = sc.nextInt();
            
            if(H==0 && W ==0)break;
            for(x = 0; x < H; x++){
            for(y = 0; y < W; y++){
                System.out.print("#");
            }
            System.out.println("");
                
            }
            System.out.println("");
        }
