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

Sample Input

Solution in JAVA (judge verdict: Accepted)

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner scn = new Scanner(System.in);
        while(true) {
            int H = scn.nextInt();
            int W = scn.nextInt();
            if(H == 0 && W == 0) {
                break;
            }
            char[] buf = new char[W];
            Arrays.fill(buf, '#');
            String lin = new String(buf);
            for(int i = 0; i < H; i++) {
                System.out.println(lin);
            }
            System.out.println();
        }
    }
