3917. Count Indices With Opposite Parity

You are given an integer array nums of length n. The score of an index i is defined as the number of indices j such that: - i < j < n, and - nums[i] and nums[j] have different parity (one is even and the other is odd). Return an integer array answer of length n, where answer[i] is the score of index i. Example 1: Input: nums = [1,2,3,4] Output: [2,1,1,0] Explanation: - nums[0] = 1, whic
