Alex and Sam are playing a weird game. The rule of this weird game is simple: there are a
total of n tasks total that Alex and Sam has to perform, labelled 0 to n-1. Alex has
to perform task 0 to k-1, while Sam has to perform task k to n-1, where k is a
number decided by Alex. For each player, if they succeed in that task, they gain 1 point,
but if they fail, they lose 1 point.
