    Given a list of delivery vehicle identification numbers, determine how many vehicle pairs can be assigned to similar geographic zones based on their VIN compatibility check. Two vehicles are considered compatible for zone pairing when the XOR operation between their VIN numbers results in an even number. Calculate the total count of such compatible vehicle pairs in the fleet.
