In this video, we walk through LeetCode 590: N-ary Tree Postorder Traversal.
We solve it in Python using a simple DFS (Depth-First Search) + Recursion approach.
We break the problem down step by step:
Understanding postorder traversal for an N-ary tree
Writing a recursive DFS function
Collecting values in the correct order
This is a clean and efficient solution with O(n) time complexity.
