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 Program
{
    static void Main()
    {
        while (true)
        {
            string[] raw = Console.ReadLine().Split(' ');
            if(raw[0]=="0")break;
            int h = int.Parse(raw[0]);
            int w = int.Parse(raw[1]);
            for(int y=0;y<h;y++){
                for(int x=0;x<w;x++)Console.Write("#");
                Console.WriteLine();
            }
            Console.WriteLine();
        }
