Data Structures and Algorithms The Complete Masterclass - Traversal (Preorder, Inorder, and Postorder)

This video tutorial covers the three main types of tree traversal methods: preorder, inorder, and postorder. It explains each method in detail, highlighting their importance in solving interview questions. The tutorial also demonstrates how to construct binary trees using traversal data, emphasizing the patterns and sequences involved. Practical tips and tricks are provided to help understand and apply these concepts effectively.
