Leetcode 3632. Subarrays with XOR at Least K

Given an array of non-negative integers and an integer K, count how many subarrays have bitwise XOR >= K. The core challenge is to efficiently count pairs of prefix-xor values whose XOR meets the threshold, typically requiring a bitwise-trie or divide-and-conquer approach to handle large n and value ranges.
