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: WA: Presentation Error)

import java.util.*;

public class Main {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        for(int i = 0; i < 300; i++) {
          String line = sc.nextLine();
          String[] l = line.split(" ");
          int H = Integer.parseInt(l[0]);
          int W = Integer.parseInt(l[1]);
          if(H == 0 && W == 0) {
            break;
          }

          for(int h = 0; h < H; h++) {
            for(int w = 0; w < W; w++) {
              System.out.print("#");
            }
            System.out.println();
          }
