Tree structure Exercise--sequential traversal of ordered binary tree Time limit:1000ms Memory limit:65536k Topic description in the tree structure, there is a special two-fork tree called the sort binary tree, the intuitive understanding is--(1). Each node contains a key value (2). The key value of any node's Zuozi (if present) is less than the key value of that node (3). The key value of t

Topic:Given a binary tree, flatten it to a linked list in-place.For example,Given 1 / 2 5 /\ 3 4 6The flattened tree should look like: 1 2 3 4 5 6Click to show hints.Hints:IF you notice carefully in the flattened tree, each node's right child points to the next node of a pre-order traversal.Answer 1: Recursive methodtrain of though

Given an array where elements is sorted in ascending order, convert it to a height balanced BST.This problem is to turn an ordered array into a binary search tree, the so-called binary search tree, is always satisfied with the left /** Definition for binary tree * struct TreeNode {* int val; * TreeNode *left; * TreeNode *right; * T Reenode (int x): Val (x), left

Binary search also known as binary search, the advantages are less than the number of comparisons, Find Fast, average performance, occupy less system memory;The disadvantage is that it requires the unknown origin table to be an ordered table, and insert Delete is difficult.Therefore, the binary lookup method is suitable for an ordered list that does not change fr

Binary lookup, also known as binary search (binary search), requires an array of ordered (sort), by comparing the intermediate data of the array (center-biased method) to determine the scope of the lookup value; Until the median value equals the lookup value, the lookup succeeds; If unsuccessful, reset the data, judge the size of the beginning and end position,
