3513. Number of Unique XOR Triplets I

LeetCodeArrayMathBit ManipulationOpen on judge ↗

You are given an integer array nums of length n, where nums is a permutation of the numbers in the range [1, n]. A XOR triplet is defined as the XOR of three elements nums[i] XOR nums[j] XOR nums[k] where i <= j <= k. Return the number of unique XOR triplet values from all possible triplets (i, j, k). Example 1: Input: nums = [1,2] Output: 2 Explanation: The possible XOR triplet values ar
