100 prisoners' problem

Yeah my code only confirms that the strategy works as predicted getting around 31% successes if followed.

Rosetta Code task asks to compare using the strategy to just randomly selecting slots with numbers until you reach 50 (failure) or you find yours 50/100 = 50:50 chance but the chance 100 people find theirs randomly is what?

.5^100 = mighty slim partner!
