Overall is the diagram represented by the transformation, by the database and Java Object Conversion , the code is relatively simple, but the pressure on the database can be a bit larger, multiple queries.The main object is to establish an association between objects No.2:maptotree ()The idea is: Use the PID(parent ID) as a grouping, so that each group's parent node is the same, in other words, the same group, all nodes PID is the same. This establishes the association for the grouping operation

The dynamic look-up trees in our presentation are: Two fork search tree (BST), Balanced binary search tree (AVL), Red black Tree (RBT), b~/b+ tree (b-tree). These four kinds of trees have the following advantages:(1) are dynamic structures. There is no need to completely reb

Finally learned the algorithm that I have admired for a long time.For the Chairman tree to be modified we just need to open one more dimension and make the revised sum. Complexity evolution to O (nlog^2n)We need to open R0 L0. Two array records the "path" of a tree-like arrayThen the other operation is the same as the Chairman tree!1#include 2 using namespacestd;

First, the definitionSome definitions: Path length between nodes: The branch that goes through the tree from one node to another, forming the number of branches on the path between the two nodes, called its path length. Tree path length: the sum of the length of the path from the root node of the tree to each node in the

guaranteed that the resources will not be distributed on Island 1th). But the investigation department also found that the machine can only use M-times, so we just need to complete each task.InputThe first line is an integer n, representing the number of islands.Next n-1 line, each line of three integer u,v,w, represents the U island and the V Island by a cost of C bridge directly connected to ensure 1Line n+1, an integer m, representing the number of times an enemy machine can be used.Next M l

Now, I want to dynamically raise some questions and modify them: the form of a question is to find the sum of all elements in a specific subinterval [a, B; the modified rule is to specify a lattice X and add or subtract a specific value. Now you are required to answer each
