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){
        Scanner scan = new Scanner(System.in);
        String str;
        int i,j;
        int a,b;
        while(true) {
            str = scan.nextLine();
            String[] num = str.split(" ", 0);
            a = Integer.valueOf(num[0]);
            b = Integer.valueOf(num[1]);
            if(a==0&&b==0){
                break;
            }
            
            for (i = 0; i < a; i++) {
                for (j = 0; j < b; j++) {
                    System.out.print("#");
                }
                System.out.println();
            }
            System.out.println();
        }
        scan.close();
