WebAug 3, 2024 · A Level Order Traversal is a traversal which always traverses based on the level of the tree. So, this traversal first traverses the nodes corresponding to Level 0, and then Level 1, and so on, from the root node. In the example Binary Tree above, the level order traversal will be: (Root) 10 -> 20 -> 30 -> 40 -> 50 WebDec 12, 2024 · Approach: In postorder traversal, the tree is traversed in this way: left, right, root. The algorithm approach can be stated as: We first recursively visit the left child and go on left till we find a node pointing to NULL. Then we return to its parent. Then we recursively visit the right child.
