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;

class Program
{
    static void Main()
    {
        for (; ; )
        {
            var line = Console.ReadLine().Split(' ');
            int H = int.Parse(line[0]);
            int W = int.Parse(line[1]);
            if (H == 0 && W == 0) break;
            for (var i = 1; i <= H; i++)
            {
                for (var j = 1; j <= W; j++) Console.Write("#");
                Console.WriteLine();
            }
            Console.WriteLine();
        }
    }
