Leetcode Question Link: https://leetcode.com/problems/xor-que...

In this video, we solve the LeetCode problem "1310. XOR Queries of a Subarray". The problem requires us to efficiently compute the XOR of elements from a subarray, for multiple queries.

We are given:

An array arr of positive integers.
A list of queries, where each query specifies two indices [lefti, righti].
Our task is to compute the XOR of all elements between the indices lefti and righti (inclusive) for each query.

Key Concepts:
XOR Operation: A bitwise operator that outputs 1 when the corresponding bits of its operands are different.
Prefix XOR: A useful trick to efficiently compute the XOR of subarrays using cumulative XOR results.
