# Level order tree traversal c++

Binary Tree Level Order Traversal. Medium. 32 Favorite Share. Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example: C++. xxxxxxxxxx. 1 /** 2 * Definition for a binary tree node. 3 * struct TreeNode {4. You are given a pointer to the root of a binary tree. You need to print the level order traversal of this tree. In level order traversal, we visit the nodes level by level from left to right. You only have to complete the function. For example: 1 \ 2 \ 5 / \ 3 6 \ 4 For the above tree, the level order traversal is 1 -> 2 -> 5 -> 3 -> 6 -> 4. Jan 05,  · Level order traversal is also called breadth first traversal for the tree. Non-Recursive solution of the problem is – Non-recursive Level Order Traversal. Approach: There are basically two functions in this method. One is to print all nodes at a given level (printLevel), and other is to get height of tree and print level wise nodes.
