1835. Find XOR Sum of All Pairs Bitwise AND Hard
1/**
2 * [1835] Find XOR Sum of All Pairs Bitwise AND
3 *
4 * The XOR sum of a list is the bitwise XOR of all its elements. If the list only contains one element, then its XOR sum will be equal to this element.
5 *
6 * For example, the XOR sum of [1,2,3,4] is equal to 1 XOR 2 XOR 3 XOR 4 = 4, and the XOR sum of [3] is equal to 3.
7 *
8 * You are given two 0-indexed arrays arr1 and arr2 that consist only of non-negative integers.
9 * Consider the list containing the result of arr1[i] AND arr2[j] (bitwise AND) for every (i, j) pair where 0 <= i < arr1.length and 0 <= j < arr2.length.
10 * Return the XOR sum of the aforementioned list.
11 *
12 * Example 1:
13 *
14 * Input: arr1 = [1,2,3], arr2 = [6,5]
15 * Output: 0
16 * Explanation: The list = [1 AND 6, 1 AND 5, 2 AND 6, 2 AND 5, 3 AND 6, 3 AND 5] = [0,1,2,0,2,1].
17 * The XOR sum = 0 XOR 1 XOR 2 XOR 0 XOR 2 XOR 1 = 0.
18 *
19 * Example 2:
20 *
21 * Input: arr1 = [12], arr2 = [4]
22 * Output: 4
23 * Explanation: The list = [12 AND 4] = [4]. The XOR sum = 4.
24 *
25 *
26 * Constraints:
27 *
28 * 1 <= arr1.length, arr2.length <= 10^5
29 * 0 <= arr1[i], arr2[j] <= 10^9
30 *
