    Given a list of user compatibility scores where each score represents a combined metric of shared interests and mutual connections, determine the number of potential user pairs that would create harmonious event matches. Two users are considered a harmonious match when the XOR of their compatibility scores results in an even number, indicating alignment in their social preferences and mutual connections.
