Hi,
Today, I find a problem from an old Google Code Jam Contest.
You can read the problem statement here :

I solved the problem in 15 min (wow, c# is very productive but...) but
my program takes a long time (1 min 15 sec) to solve the example 5 (see
the problem statement).
I found a C++ program that uses the same method than my program.
However, this program is a lot faster : it solves the example 5
in...0sec.

I can't understand why my C# program takes more than 1 minutes since
they use the same method.

Man, it's really embarrassing -_-
Hope it's my fault and not the .net framework fault.

My PC Configuration:
     - AMD Athlon XP 2800+
     - Windows XP Pro SP2
     - .Net framework 2.0
     - Visual C# Express 2005 and Visual C++ Expresss 2005
