HackerEarth Pile of Coins problem solution

In this HackerEarth Pile of Coins problem solution, Ashish and Jeel are playing a game. They are given two piles of coins with P and Q coins respectively. They take alternate turns. During each turn, the player can choose one pile and split it into two non-zero parts, and discard the other pile that is not chosen. The discarded pile cannot be used further in the game. A player loses if he cannot make a move. Both the players play the game optimally. You are given P and Q. Determine who wins the game if Ashish plays first.
