Determine the Winner of the Maximum Stones Game

In the Maximum Stones Game, two piles of stones are given. The game rules are straightforward: if the number of stones in the two piles are different, then Alice wins; if they are the same, then Bob wins. Formally, given two integers (A) and (B), if (A \neq B) then the winner is Alice, otherwise the winner is Bob.

Your task is to write a program that reads two integers from the standard input and prints the winner's name to the standard output.

inputFormat

The input consists of a single line with two space-separated integers (A) and (B) representing the number of stones in the first and second pile respectively.

outputFormat

Output a single string which is either "Alice" if (A \neq B) or "Bob" if (A = B).## sample
