Binary tree traversal is a fundamental operation in computer science, visiting each node in the tree in a specific order. This article covers four essential traversal methods with both recursive and iterative implementations. Preorder Traversal (Root-Left-Right) Preorder traversal visits the root node first, then the left subtree, followed by t ...

1. Binary Tree Categories Full Binary Tree: A binary tree where all nodes have either 0 or 2 children, and all leaf nodes are at the same level. For depth k, the tree contains (2^k - 1) nodes. Complete Binary Tree: A binary tree where all levels except possibly the last are completely filled, and all nodes are as far left as possible. Binary Se ...
