1310. XOR Queries of a Subarray

You are given an array arr of positive integers. You are also given the array queries where queries[i] = [lefti, righti]. For each query i compute the XOR of elements from lefti to righti (that is, arr[lefti] XOR arr[lefti + 1] XOR ... XOR arr[righti] ). Return an array answer where answer[i] is the answer to the ith query. Example 1: Input: arr = [1,3,4,8], queries = [[0,1],[1,2],[0,3],[3,3
