p04037 AtCoder Grand Contest 002 - Candy Piles
There are N piles of candies on the table. The piles are numbered 1 through N. At first, pile i contains a_i candies.

Snuke and Ciel are playing a game. They take alternating turns. Snuke goes first. In each turn, the current player must perform one of the following two operations:

1. Choose a pile with the largest number of candies remaining, then eat all candies of that pile.
2. From each pile with one or more candies remaining, eat one candy.



The player who eats the last candy on the table, loses the game. Determine which player will win if both players play the game optimally.
