Number Game RevisitedProblem code: NUMGAME2 |
All submissions for this problem are available.
Alice and Bob play the following game.They choose a number N to play with.The runs are as follows :
1.Bob plays first and the two players alternate.
2.In his/her turn ,a player can subtract from N any prime number(including 1) less than N.The number thus obtained is the new N.
3.The person who cannot make a move in his/her turn loses the game.
Assuming both play optimally,who wins the game ?
Input format:
The first line contains the number of test cases T.Each of the next lines contains an integer N.
Output format:
Output T lines one for each test case,containing "ALICE" if Alice wins the game ,or "BOB" if Bob wins the game.
Example
Sample Input: 2 1 2
Sample Output: ALICE BOB
Constraints: 1 <= T <= 1000000 1 <= N <= 1000000000
Note : For the first test case, Bob cannot make any move and hence Alice wins the game. For the second test case, Bob subtracts 1 from N. Now, Alice cannot make a move and loses the game.
