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 AizuOnLine
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                string[] data = Console.ReadLine().Split(' ');
                int h = Convert.ToInt32(data[0]);
                int w = Convert.ToInt32(data[1]);

                if (h == 0 && w == 0) { break; }

                for (int x = 0; x < h; x++)
                {

                    Console.WriteLine(new String('#', w));
                }

                Console.WriteLine(string.Empty);
            }
        }
