NPC2014A - I Ken Bit Yu

On a hot day in Surabaya, Puguh is bored. He then declares himself as "the bestest player in teh wurld", challenging his friend named Joke to play a game. Here is the description of the game:

  • There are N piles of coins and each pile contains Xi coins (i=1 to N).
  • Each player alternately takes turn.
  • On each turn, a player must take a number of coin from any pile. The number of coin taken must be a divisor of the current pile size and must be less than the current pile size. For example, if Puguh chooses a pile with 6 coins, then he may take 1, 2, or 3 coins from that pile.
  • The first player that can't take any coin on his turn loses.

Puguh and Joke will play optimally. If Puguh is the first player to move, predict the winner of this game.



Input starts with a number T, the number of test cases. For each test case, the first line contains a number N. The next line contains N numbers Xi, number of coins on the i-th pile.


For each case, output a line. If Puguh won the game, output "Puguh is the bestest player in teh wurld" and if Joke won the game, output  "Joke is the bestest player in teh wurld".

Sample Input


Sample Output

Puguh is the bestest player in teh wurld


  • 1 ≤ T ≤ 50
  • 0 ≤ N ≤ 100000
  • 0 ≤ Xi ≤ 1000000000

Input file is huge, use faster I/O (scanf for C)

@surayans tiwari: 0 is a terminal i.e losing position

It's worth clarifying that the number of coins you take must be a divisor of the current pile size (as opposed to the original Xi value), and that there are of course no valid moves for an empty pile.

Andy: updated the description, thanks!
