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

using System;

namespace ITP1_5_A
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                var input = Console.ReadLine();
                var values = input.Split(' ');
                int H = int.Parse(values[0]);
                int W = int.Parse(values[1]);
                if (H == 0 && W == 0) break;

                for(int i=1;i<=H;i++)
                {
                    for(int j=1;j<=W;j++)
                    {
                        Console.Write("#");
