the fast pointer to find the midpoint of the list, the left half of the list ends point to null, and recursively constructs a left subtree. The right half of the part is built recursively into the right sub-tree. If you do not want to destroy the original linked list, then you can use the first to save to the array and then build the method.1 PublicTreeNode Sortedlisttobst (ListNode head) {2 if(head==NULL)3 return NULL;4

First, describeThis paper analyzes and compares the binary search algorithm of JDK and the common binary search algorithm written by itself, uses bits unsigned right shift to replace the 2 operation, and uses the method of generating random number to produce a range of random number array, and calls the sort () static

, and the right child node's key is greater than or equal to the parent node. Two forks the search tree when inserting can directly change the left tree right tree pointer pointing, the search can be based on the characteristics of binar

?? The previous article described the implementation of the two-fork lookup tree, where the insert operation is implemented using a non-recursive method, where a recursive implementation of the insert operation, the Java code is as follows, it is recommended to add to the previous article corresponding to FOBinarySearchTree.java ;

Direct sorting is then stored in the list, and the code is simple and efficient. (refer to discuss).This method is faster

, compared to the root node, and, if not equal to the root node, recursively traverses the left subtree or the right subtree, depending on the value of the lookup and the size of the root node. Until the lookup value is found, the result is output.When a binary sort tree is inserted, the value directly to be inserted is stored in an array using the ArrayList linked list, iterating through the array, passing
