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

Sample Input

Solution in C# (judge verdict: Accepted)

using System;

class Rectangle
{
    public static void Main()
    {
        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;
            }

            for (int i = 0; i < H; i++)
            {
                for (int j = 0; j < W; j++)
                {
                    Console.Write("#");
                }
                Console.WriteLine();
            }
            Console.WriteLine();
        }
    }
