Binary Tree Level Order Traversal Total Accepted: 79463 Total Submissions: 259292 Difficulty: Easy Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example:Given binary tree {3,…

Problem Description As we know,the shape of a binary search tree is greatly related to the order of keys we insert. To be precisely: 1. insert a key k to a empty tree, then the tree become a tree with only one node; 2. insert a key k to a nonempty tr…
