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

Solution in C# (judge verdict: Accepted)

using System;

class Program {
    private static int Main() {
        while( true ) {
            var input = Console.ReadLine();
            var values = input.Split( ' ' );

            int H = int.Parse( values[ 0 ] );
            int W = int.Parse( values[ 1 ] );

            if( H == 0 && W == 0 ) { break; }

            var output = new string( '#', W );
            for( int i = 0; i < H; ++i ) {
                Console.WriteLine( output );
            }
            Console.WriteLine();
        }

        return 0;
    }
}
