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 Program {
    static void Main( string[] args )
    {
        while ( true ) {
            string[] input = Console.ReadLine().Split();

            int h = int.Parse( input[ 0 ] );
            int w = int.Parse( input[ 1 ] );

            if ( 0 == h + w ) {
                break;
            }

            string s = new string( '#', w );

            for ( int i = 0; i < h; ++i ) {
                Console.WriteLine( s );
            }

            Console.WriteLine();
        }
    }
}
