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 s = new Scanner(System.in);
    int h = s.nextInt();
    int w = s.nextInt();
    while (h != 0 && w != 0) {
      for (int i = 0; i < h; i++) {
        String st = "";
        for (int j = 0; j < w; j++) {
          st += "#";
        }
        System.out.println(st);
      }
      System.out.println();
      h = s.nextInt();
      w = s.nextInt();
    }
    s.close();
  }
