It is not difficult to find that each operation is equivalent to merging the connected components sequentially in two intervals, if the violent merger is clearly O (NM). What do we do? We set up the St table for the sequence so that we can understand it as a nlogn point, merging chunks first, then recursively merging small chunks. Note that each po

the merger in front of it (that is, the second Werbe query point Large) and the third Werbe ask the point of the big point will have a 1 contribution to the inquiry point.

When a sequence contains only a link to its successor, it is called a single-linked list. This article mainly introduced the PHP implementation of single-linked list flipping operation, combined with the example of the analysis of the PHP single-linked list of the definition, traversal, recursion, flip and other related operations skills, the need for friends can refer to, hope to help everyone. Here is a definition of a single-linked list and how to flip it: Operation Result: 0 1 2 3 4 5 6
