WebMar 12, 2024 · Recursive Approach: The idea is to traverse the tree in a Level Order manner but in a slightly different manner. We will use a variable flag and initially set it’s value to zero. As we complete the level order traversal of the tree, from right to left we will set the value of flag to one, so that next time we can traverse the Tree from left ... WebFor traversing a (non-empty) binary tree in pre-order fashion, we must do these three things for every node N starting from root node of the tree: (N) Process N itself.

WebMay 24, 2024 · Binary Trees study guide. Prerequisites that you should be familiar with before : Recursion, stack, queue. A basic instinct for solving DFS based questions is to do a recursive call and for all BFS (level order traversal) is to make queue and iterate, but also think upon how to iterate in DFS (Hint think on stack) and recurse in BFS based. WebThe reason this doesn't work is that res only has the value of the first node you give it appended to it; each time you recursively recall the function, it just makes a new res. It is a simple fix though, as follows: class Solution(object): def inorderTraversal(self, root): res = [] if root: res = self.inorderTraversal(root.left) res.append(root.val) res = res + …
