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 ConsoleApplication13
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true) {
            String[] s = Console.ReadLine().Split(' ');
            int H = int.Parse(s[0]);
            int W = int.Parse(s[1]);

            if (H == 0 && W == 0) break;
                int i = 0;
                while (true)
                {
                    if (i == H) break;
                    for (int x = 0; x < W; x++)
                    {
                        Console.Write("#");
                    
                    }
                    Console.WriteLine();

                    i++;
                }
