  "task_description": "You are given two **0-indexed** arrays, `nums1` and `nums2`, consisting of non-negative integers. Let there be another array, `nums3`, which contains the bitwise XOR of **all pairings** of integers between `nums1` and `nums2` (every integer in `nums1` is paired with every integer in `nums2` **exactly once**). Return_ the **bitwise XOR** of all integers in _`nums3`. **Example 1:** ``` **Input:** nums1 = [2,1,3], nums2 = [10,2,5,0] **Output:** 13 **Explanation:** A possible nums3 array is [8,0,7,2,11,3,4,1,9,1,6,3]. The bitwise XOR of all these numbers is 13, so we return 13. ``` **Example 2:** ``` **Input:** nums1 = [1,2], nums2 = [3,4] **Output:** 0 **Explanation:** All possible pairs of bitwise XORs are nums1[0] ^ nums2[0], nums1[0] ^ nums2[1], nums1[1] ^ nums2[0], and nums1[1] ^ nums2[1]. Thus, one possible nums3 array is [2,5,1,6]. 2 ^ 5 ^ 1 ^ 6 = 0, so we return 0. ``` **Constraints:** `1 <= nums1.length, nums2.length <= 105` `0 <= nums1[i], nums2[j] <= 109`",
