Rovers on Mars

Somebody asked me to code the solution for a problem called "MARS ROVERS".
Somehow I could do it... and I blogged it here...

Feel free to use, publish, steal, submit it as your own solution somewhere else or do anything with it.

footnote: Watson says "Process and documentation is what a software engineer has more than coolies. Code quality and other bullshit is more important than wit, logic, hacks and skills".
I say "Watson SUCKS".
