The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article and later in this article ensures that the LGN efficiency can be achieved in the worst case, and we need to make sure

root of the subtree has several apples (including the I node).AnalysisStep 1 :As can be seen, because the normal tree does not have the nature of the interval, so when considering the use of line tree as a solution, we need to transform the given data, first a DFS traversal of the tree, the start and end time of each point in the DFS sequence is recorded, the st

Two-fork tree with a depth of k up to 2^ (k)-1 nodes (k>=1)
Property 3
for any binary tree T, if its terminal node is N0, the number of nodes with a degree of 2 is n2 n0 = n2 + 1The total number of tree T nodes

Tree structure-tree structure data storage and database table designTree structure is generally used in the infinite class classification, whether you use Java,.net,php,python and other language platforms for development and application,

order of the data in the clustered index is consistent with the index order, that is, as long as the index is adjacent, the corresponding data must also be stored on the disk adjacent to it. If the primary key is not an ID, imagine what it will do, constantly adjust the physical address of the data, paging, and of course there are other measures to reduce these operations, but it can not be completely avoided. However, if it is a self-added, it is simple, it only needs a page to write, the inde

problem Description
Given two trees T1 and T2. If T1 can be converted to T2 by several times or so, we call the two trees "isomorphic". For example, the two trees given in Figure 1 are isomorphic because we swap the children of the nodes A, B, and g of one of the trees to get another

Last time we looked together. The sparse matrix compression storage and the implementation of some basic operations of matrix based on ternary table storage structure. This time, let's take a look at the tree. The most important data structure-the implementation of the two-fork list storage structure of the two-fork

(starting from 1th instead of starting from 0th), for a node numbered I we can determine whether he is the left node or the right node, who is the parent node, who is the child node, according to the size of I. For example, we give a number 13 node, then he is odd so he is the right node, because the node changes and the parity of the data is a synchronous change. His parent node is 13/2=6 (starting from number 1th) his left child node is the 13*2=26 right child node is 13*2+1=27 also can beg h
