equivalent to no reversal, so just consider those reversal odd number of times.Full code:#include C.Topic Link: Click to open the linkProblem Solving Ideas:The C-question feeling is simpler than the B question, the first idea of reading the question is to order, then the next comparison, then do and. The only possible problem is that the data is too big to worry long long, so open to unsigned long long.But this problem also has a pit, that is not necessarily adjacent to the two comparisons, bec
