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 Test
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            while (true)
            {
                var inputs = Console.ReadLine().Split(' ');
                var nums = Array.ConvertAll(inputs, int.Parse);
                if ((nums[0] | nums[1]) == 0) return;

                var H = nums[0];
                var W = nums[1];
                const char block = '#';

                for (int i = 0; i < H; i++)
                {
                    Console.WriteLine(new String(block, W));
                }
                Console.WriteLine();
            }
