Title Link: Http://codeforces.com/contest/505/problem/DMain topic:In one figure, there are n vertices, giving the m pair number (U,V) to indicate that the vertex u and vertex v must be connected directly or indirectly, so that you can construct a graph with a minimum number of edges required for the output. Analysis:Without a doubt, n vertices, we can use up to n edges, so that n vertices form a ring to satisfy all the situation (any two points are connected), but this is not necessarily the lea

first, the implementation of the plan buffer　　The optimizer-generated execution plan is saved in a special part of the SQL Server memory pool, known as a plan buffer or process buffer. process buffering is part of the SQL Server cache. Saving a plan in buffering allows SQL Server to avoid having to re-submit the same query again through the entire query optimization process.
