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;
class Main {
    public static void main (String[] args) {
        Scanner sc = new Scanner(System.in);
        while (true) {
        	int a = sc.nextInt();
        int b = sc.nextInt();
        if (a==0 && b==0) break;
        for (int i=0; i<a; i++) {
        		for(int j=0; j<b;j++) {
        			System.out.print("#");
        			if(j == b-1) System.out.println();
        		}
        		if(i == a-1) System.out.println();
        }
        }
    }
