Tree Traversal

Tree traversal is a fundamental algorithm concept in computer science that involves systematically visiting and processing each node in a tree data structure exactly once. It is essential for operations like searching, sorting, and hierarchical data manipulation. Common traversal methods include depth-first (e.g., in-order, pre-order, post-order) and breadth-first approaches.

Also known as: Tree walking, Tree search, Node traversal, Hierarchical traversal, BST traversal

Why learn Tree Traversal?

Developers should learn tree traversal for tasks involving hierarchical data, such as parsing expressions in compilers, navigating file systems, or implementing search algorithms in databases. It is crucial in data structures like binary search trees, DOM manipulation in web development, and AI decision trees, enabling efficient data access and processing.
