1803. Count Pairs With XOR in a Range

LeetCodeArrayBit ManipulationTrieOpen on judge ↗

Given a (0-indexed) integer array nums and two integers low and high, return the number of nice pairs. A nice pair is a pair (i, j) where 0 <= i < j < nums.length and low <= (nums[i] XOR nums[j]) <= high. Example 1: Input: nums = [1,4,2,7], low = 2, high = 6 Output: 6 Explanation: All nice pairs (i, j) are as follows: - (0, 1): nums[0] XOR nums[1] = 5 - (0, 2): nums[0] XOR nums[2] = 3 - (
