CF1841A Game with Board
Description
Alice and Bob play a game. They have a blackboard; initially, there are $ n $ integers written on it, and each integer is equal to $ 1 $ .
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\} $ , then the following moves are possible:
- choose two integers equal to $ 1 $ , wipe them and write an integer $ 2 $ , then the board becomes $ \{2, 2, 2, 2, 3\} $ ;
- choose two integers equal to $ 2 $ , wipe them and write an integer $ 4 $ , then the board becomes $ \{1, 1, 2, 3, 4\} $ ;
- choose three integers equal to $ 2 $ , wipe them and write an integer $ 6 $ , then the board becomes $ \{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 Format
The first line contains one integer $ t $ ( $ 1 \le t \le 99 $ ) — the number of test cases.
Each test case consists of one line containing one integer $ n $ ( $ 2 \le n \le 100 $ ) — the number of integers equal to $ 1 $ on the board.
Output Format
For each test case, print Alice if Alice wins when both players play optimally. Otherwise, print Bob.
Explanation/Hint
In the first test case, $ n = 3 $ , so the board initially contains integers $ \{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 $ 1 $ , wipes them and writes $ 2 $ , the board becomes $ \{1, 2\} $ . Bob cannot make a move, so he wins;
- if Alice chooses three integers equal to $ 1 $ , wipes them and writes $ 3 $ , the board becomes $ \{3\} $ . Bob cannot make a move, so he wins.
In the second test case, $ n = 6 $ , so the board initially contains integers $ \{1, 1, 1, 1, 1, 1\} $ . Alice can win by, for example, choosing two integers equal to $ 1 $ , wiping them and writing $ 2 $ on the first turn. Then the board becomes $ \{1, 1, 1, 1, 2\} $ , and there are three possible responses for Bob:
- if Bob chooses four integers equal to $ 1 $ , wipes them and writes $ 4 $ , the board becomes $ \{2,4\} $ . Alice cannot make a move, so she wins;
- if Bob chooses three integers equal to $ 1 $ , wipes them and writes $ 3 $ , the board becomes $ \{1,2,3\} $ . Alice cannot make a move, so she wins;
- if Bob chooses two integers equal to $ 1 $ , wipes them and writes $ 2 $ , the board becomes $ \{1, 1, 2, 2\} $ . Alice can continue by, for example, choosing two integers equal to $ 2 $ , wiping them and writing $ 4 $ . Then the board becomes $ \{1,1,4\} $ . The only possible response for Bob is to choose two integers equal to $ 1 $ and write $ 2 $ instead of them; then the board becomes $ \{2,4\} $ , Alice cannot make a move, so she wins.
