Then the numbers from small to large sorting, in line with the order to find students to do the investigation. Please help clearly to co
http://poj.org/problem?id=2773 (Topic link)Test instructions: Give two number m,k, ask to find the number of K from 1 and M coprime.SolutionThe data range is very large, direct simulation is obviously not possible, we need to use some strange methods.Consider whether the solution can be quickly obtained in some way, but there is no clue. It is difficult to reverse, can not be calculated by the number of M coprime to get the number of coprime? The answer is workable, and we can use the repulsion.
