tree traversal

Tree traversal refers to the process of visiting and accessing every node in a tree data structure. It involves systematically exploring the nodes in a specific order, ensuring that every node is reached and processed. Tree traversal is commonly used in algorithms and applications that require examining or manipulating the elements in a tree-like structure. Different traversal techniques include depth-first traversal (e.g., in-order, pre-order, and post-order) and breadth-first traversal (also known as level-order traversal).
