XOR logic - suppose you have a^b^c^d^e and you need to only find value of c^d^e, xor it with a^b( index of this is prefix array will be at pref[queries[currentindex][0]-1]. Time complexity O(m n) where m is size of array and n of queries. Solution: leetcode.com/problems/xor-queries-of-a-subarray/solutions/5781303/use-xor-property/
