Introduction :The definition of trimming and cutting points is limited to the non-direction diagram. We can solve all the cut and cut edges of the non-direction graph by the definition of brute force, but the method is inefficient. Tarjan presents a quick solution to solve all the cutting and cutting edges in the graph through a Dfs.Welcome to discuss, if there a

In this article, we briefly introduce the concepts related to the cutting point, cutting edge and dichotomy diagram of the solution graph.Cut point:For the connected undirected graph G with n points and m edges, if the vertex VI is removed (and the edge is removed at the same time) so that G is no longer connected, then the VI is a cut point.By its definition, it is not difficult to determine whether a poin

Centos large file cutting and merging, centos cutting and merging Many companies now place projects on ECS. When I want to put down the code and generated file "sz file name" in the ECS, I find it too large. ECS does not support downloading large files. In this case, you need to use the split command to cut the file, then go down, merge it locally or upload it to the desired server, and then merge it. The
