the LCA down, put the X into a proper spot, kick the x out, and add the P in.Loop to do, set the top of the stack below the element is Y, if:1.DFN[Y]>DFN[LCA], i.e. LCA on y, that gives y and x a side, then kicks X to continue doing2.DFN[Y]=DFN[LCA], then LCA is already in the virtual tree, give y and x side, kick X and break on the line3.DFN[Y]Finally, the p is also pressed into the stack. Note that the path information is also recorded on the edge

Definition: A graph with a direction, a minimum spanning tree that exists at the root of a point and can reach all points, is the smallest tree.Zhu Liu Algorithm implementation process: "After the selection of the edge set (see Step 1), if there is no direction to the graph, the graph is the minimum tree chart"1, select the edge set--Find all the points in addition to the root point, the minimum weight of e

and m, respectively, indicating the number of caves and the number of instructions appearing on the terminal. The following m lines, in turn, represent the instructions that appear on the terminal. Each line begins with a string s ("Connect", "Destroy", or "Query") representing the type of instruction, followed by two integers u and V (1≤u, V≤n and U≠v) representing the number of the two caves respectively.OutputFor each query command, the output cave U and Cave v are interconnected: the output

After a 3-day train ride, I finally got to my ┬_┬. This trip to Beijing is quite touching, although the things learned are not many (mainly their own reasons, no serious study, not the teacher said bad), but go out to see the world is also good. The last game was quite impressive, a bit miserable to be abused .... Remember at that time a problem feel oneself can, want to use the array to simulate chain list water over, but no matter how optimization has been timed out @[email protected] back tha
