# 1) If either pile is 1, Alice wins immediately:
if A == 1 or B == 1:
    print("Alice")
# 2) Otherwise, if A < B, Alice is forced into a losing "race":
elif A < B:
    print("Bob")
# 3) Otherwise, if A = B+1, every move hands Bob a win:
elif A == B + 1:
    print("Bob")
# 4) In all other cases, Alice has a winning move:
else:
    print("Alice")
