Main topicGive a tree, ask to choose three points, so that the distance between the three points equal to the scheme of how many kinds.IdeasThese three points must not be a chain again, then it is certainly possible to determine a central point, so that the distance between the three points to the center point is equal.Then we can enumerate the center point and count it for each depth. Although it looks like a O ( n 3 ) , but it's a running flight.CODE#define _crt_secure_n

Segment Tree section of the merge, there is a segment, from 1 to N, the following m operations, operations are divided into two types, 1 is the query operation, beginning with 2 is the update operation1 W indicates that an interval of W is queried within the total interval, and that the left end of the interval is returned to the left, and that the interval is not found, and it is not found to return 0.Nearly 2 months not how to learn algorithm brush problem, also dropped a lot of things, slowly
