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.Scanner;

class Main{
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);

    int H, W;
    int times=0;

    while(true){
      H = sc.nextInt();
      W = sc.nextInt();
      if(H==0 && W==0) break;

      for (int i=0; i<H; i++) {
        for (int j=0; j<W; j++) {
          System.out.printf("#");
        }
        System.out.printf("\n");
      }
      System.out.printf("\n");
      //times++;
    }

    /*for (int k=0; k<times; k++) {
      for (int i=0; i<H; i++) {
        for (int j=0; j<W; j++) {
          System.out.printf("#");
        }
        System.out.printf("\n");
      }
    }*/
