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 AOJ
{
    public static void Main()
    {
        while (true)
        {
            string[] st = Console.ReadLine().Split(' ','\n');
            int a = int.Parse(st[0]);
            int b = int.Parse(st[1]);
            if (a == 0 && b == 0)
                break;
            for (int i = 0; i < a; i++)
            {
                for (int j = 0; j < b; j++)
                {
                    Console.Write("#");
                }
