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

using System;
using System.Collections.Generic;

class Program
{
    static void Main(string[] args)
    {

        String[] str = Console.ReadLine().Split(' ');

        char[,] ary = new char[int.Parse(str[0]), int.Parse(str[1])];

        for (int i = 0; i < ary.GetLength(0); i++)
        {
            for (int j = 0; j < ary.GetLength(1); j++)
            {
                ary[i, j] = '#';
            }
        }

        for (int i = 0; i < ary.GetLength(0); i++)
        {
            for (int j = 0; j < ary.GetLength(1); j++)
            {
                Console.Write(ary[i, j]);
            }
            Console.Write("\r\n");
