Traversal (Preorder, Inorder, and Postorder)

The video tutorial covers the three main types of tree traversals: preorder, inorder, and postorder. It explains each traversal method in detail, providing examples and discussing their importance in solving interview questions. The tutorial also demonstrates how to use these traversal methods to construct binary trees, emphasizing the patterns and logic behind each method. The video concludes with a recommendation to practice these concepts to gain a deeper understanding.
