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

using System;

namespace ConsoleApplication7
{
    class Program
    {
        static void Main(string[] args)
        {
           while(true)
           {

                string Date = Console.ReadLine();
                string[] date = Date.Split(' ');
                int H = int.Parse(date[0]);
                int W = int.Parse(date[1]);

                if (H == 0 && W == 0)       //H,W??±???0????????????
                {
                    break;
                }
                for(int i = 1; i <= H; i++)
                {
                    for (int n = 1; n < W; ++n)
                    {
                        Console.Write("#");
                    }
                    Console.WriteLine("#");
