🔁 Preorder Traversal in Binary Trees (Root → Left → Right)
Preorder traversal is a way to visit every node in a binary tree in the order: Root → Left → Right That means we: 1️⃣ Visit the current node first 2️⃣ Traverse the entire left subtree 3️⃣ Traverse the entire right subtree It's used for: * Copying or serializing a tree structure * Evaluating expression trees (prefix notation ...

Preorder tree traversal, inorder tree traversal, and postorder tree traversal computer science concept explained in under 5 minutes. This is the easiest way IMO to remember all 3 of them. At the root of the tree, start traversing for all 3 methods counterclockwise. From there, preorder requires you the first time seeing the node to print it, inorder is the second time, post is the last time. Make sure to draw out the nulls when doing this yourself so you do the traversals correctly. #leetcode #t
