Alice and Bob raised their own ants. Alice has ants, while Bob has ants. Alice and Bob stand at opposite ends of an infinitesimally wide string and let all of their ants onto the string: Alice's ants all start walking towards Bob, and Bob's ants all start walking towards Alice. Every ant walks at the same constant speed, and an ant only ever turns around when it runs into another ant, in which case both ants bounce back and reverse direction. Find the total number of collisions between ants that take place.
