Solution in JAVA (judge verdict: Accepted)

import java.util.*;

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