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;

public class Hello
{
    public static void Main()
    {
        while (true)
        {
            string[] line = Console.ReadLine().Trim().Split(' ');
            var h = int.Parse(line[0]);
            var w = int.Parse(line[1]);
            if (h == 0 && w == 0) break;
            var s = new string('#', w);
            for (int i = 0; i < h; i++) Console.WriteLine(s);
            Console.WriteLine();
        }
    }
