Nettet25. feb. 2016 · CF 617E XOR and Favorite Number ( Mo's Algorithm ) For a range query [ ql, qr ], we are asked to find the number of distinct pairs that XOR to a given number K. Since it is a range XOR problem, we will consider precomputing prefix XOR pa for the original array a. Now the problem transforms to counting the number of pairs ( i, j ) that … Nettet19. jan. 2024 · The idea of MO’s algorithm is to pre-process all queries so that result of one query can be used in next query. Below are steps. Let a [0…n-1] be input array and q [0..m-1] be array of queries. Sort all queries in a way that queries with L values from 0 to √n – 1 are put together, then all queries from √n to 2*√n – 1, and so on. clickmeeting co to jest https://salermoinsuranceagency.com
