Given the array arr of positive integers and the array queries where queries[i] = [Li, Ri], for each query i compute the XOR of elements from Li to Ri (that is, arr[Li] xor arr[Li+1] xor ... xor arr[Ri] ). Return an array containing the result for the given queries. ...
地址https://leetcode-cn.com/problems/xor-queries-of-a-subarray/ 有一个正整数数组 arr,现给你一个对应的查询数组 queries,其中 queries[i] = [Li, Ri]。 对于每个查询 i,请你计算从 Li 到 Ri 的 XOR 值(即 arr[Li] xor arr[Li+1] xor ... xor arr[Ri])作为本次查询的结果。 并返回一个...

Chef always likes to play with arrays. He came up with a new term"magical subarray". A subarray is called magical if its starting index is 1 (1-based indexing). Now, Chef has an array of N elements and 2 types of queries:
