Game with Board

Alice and Bob play a game. They have a blackboard; initially, there are nn integers written on it, and each integer is equal to 11.

Alice and Bob take turns; Alice goes first. On their turn, the player has to choose several (at least two) equal integers on the board, wipe them and write a new integer which is equal to their sum.

For example, if the board currently contains integers {1,1,2,2,2,3}\{1, 1, 2, 2, 2, 3\}, then the following moves are possible:

  • choose two integers equal to 11, wipe them and write an integer 22, then the board becomes {2,2,2,2,3}\{2, 2, 2, 2, 3\};
  • choose two integers equal to 22, wipe them and write an integer 44, then the board becomes {1,1,2,3,4}\{1, 1, 2, 3, 4\};
  • choose three integers equal to 22, wipe them and write an integer 66, then the board becomes {1,1,3,6}\{1, 1, 3, 6\}.

If a player cannot make a move (all integers on the board are different), that player wins the game.

Determine who wins if both players play optimally.

Input

The first line contains one integer tt (1t991 \le t \le 99) — the number of test cases.

Each test case consists of one line containing one integer nn (2n1002 \le n \le 100) — the number of integers equal to 11 on the board.

Output

For each test case, print Alice if Alice wins when both players play optimally. Otherwise, print Bob.

Note

In the first test case, n=3n = 3, so the board initially contains integers {1,1,1}\{1, 1, 1\}. We can show that Bob can always win as follows: there are two possible first moves for Alice.

  • if Alice chooses two integers equal to 11, wipes them and writes 22, the board becomes {1,2}\{1, 2\}. Bob cannot make a move, so he wins;
  • if Alice chooses three integers equal to 11, wipes them and writes 33, the board becomes {3}\{3\}. Bob cannot make a move, so he wins.

In the second test case, n=6n = 6, so the board initially contains integers {1,1,1,1,1,1}\{1, 1, 1, 1, 1, 1\}. Alice can win by, for example, choosing two integers equal to 11, wiping them and writing 22 on the first turn. Then the board becomes {1,1,1,1,2}\{1, 1, 1, 1, 2\}, and there are three possible responses for Bob:

  • if Bob chooses four integers equal to 11, wipes them and writes 44, the board becomes {2,4}\{2,4\}. Alice cannot make a move, so she wins;
  • if Bob chooses three integers equal to 11, wipes them and writes 33, the board becomes {1,2,3}\{1,2,3\}. Alice cannot make a move, so she wins;
  • if Bob chooses two integers equal to 11, wipes them and writes 22, the board becomes {1,1,2,2}\{1, 1, 2, 2\}. Alice can continue by, for example, choosing two integers equal to 22, wiping them and writing 44. Then the board becomes {1,1,4}\{1,1,4\}. The only possible response for Bob is to choose two integers equal to 11 and write 22 instead of them; then the board becomes {2,4}\{2,4\}, Alice cannot make a move, so she wins.
