An ordered tree with a maximum of two Subtrees is calledBinary Tree. Binary Tree is a specialTree.
Recursive definition: a binary tree is a set of n (n> = 0) finite nodes. N = 0 is called an empty

Title: The pre-sequence traversal and the middle sequence traversal of a given binary tree, generating a two-fork tree.Example:Pre-sequence traversal array: prearr[]:{1,2,4,5,3,6,7}Middle Sequence Traversal array: inarr[]:{4,2,5,1,6,3,7}The resulting two fork tree is as follows:Problem Solving Ideas:By the nature of the pre-order variables of the two-fork
Binary sorting tree and the transformation of the balanced binary tree start to see the video alone when the feeling is clear, but see the problem is at a loss, if one-way rotation can also, encounter LR type and RL type is difficult, so be sure to write a blog to understand it. This blog will first introduce the
Thought: For the two-fork sort tree , in which the sequence traversal sequence is an ascending ordered sequence , so, for a given two-fork tree in the middle sequence traversal, if the previous value can always be kept smaller than the latter value, then the two fork tree is a binary sort

The search of the binary sorting tree belongs to the category of dynamic search. Based on whether the table is modified during the search process, the search can be
