Tree traversals are methods of visiting all nodes in a tree data structure.

• There are three types of tree traversals: in-order, pre-order, and post-order.

• In-order traversal visits the left subtree, then the root, then the right subtree.

• Pre-order traversal visits the root, then the left subtree, then the right subtree.

• Post-order traversal visits the left subtree, then the right subtree, then the root.

• Tree traversals are commonly used in searching and sorting algorithms.
