3854. Minimum Operations to Make Array Parity Alternating

You are given an integer array nums. An array is called parity alternating if for every index i where 0 <= i < n - 1, nums[i] and nums[i + 1] have different parity (one is even and the other is odd). In one operation, you may choose any index i and either increase nums[i] by 1 or decrease nums[i] by 1. Return an integer array answer of length 2 where: - answer[0] is the minimum number of opera
