The Game of Nim is a famous studied 2 player strategy game. http://en.wikipedia.org/wiki/Nim
There are 3 heaps, and you are given the number of pebbles in each heap. Player 1 and 2 take turns removing pebbles from each heap. Game ends when a player cannot remove any pebbles from any heap, and the last player able to do so is the winner.
Given the number of pebbles in each heap, determine if player-1 will win assuming that both player play their optimal strategy, ie their best possible moves.
