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

Solution in C# (judge verdict: WA: Presentation Error)

using System;

class program
{
    public static void Main()
    {
        while (true)
        {
            var str = Console.ReadLine().Split(' ');
            var H = int.Parse(str[0]);
            var W = int.Parse(str[1]);

            if (H == 0 && W == 0) break;

            for (int height = 0; height < H; height++)
            {
                for (int width = 0; width < W; width++)
                {
                    Console.Write('#');
                }
                Console.WriteLine();
            }
            Console.WriteLine();
        }
        Console.WriteLine();
