Invert Binary Tree – Part 2

The video tutorial explains the process of inverting a binary tree using recursion. It begins with an introduction to the concept of tree inversion, followed by a detailed explanation of swapping subtrees. The tutorial then delves into the recursive process of inverting tree nodes, emphasizing the importance of base cases to prevent infinite loops. The video concludes with a summary of key concepts, including recursion, base cases, and the structure of binary trees.
