LeetCode Problem: N-ary Tree Post-Order Traversal | Recursive C# Solution Explained

Here's my solution to the LeetCode Problem: N-ary Tree Post-Order Traversal, implemented in C# using a Recursive Approach. 🚀

💡 Problem Overview:
The task is to perform a post-order traversal on an N-ary tree, where nodes may have multiple children, traversing in the order all children → root. This recursive solution simplifies complex tree structures into manageable traversal steps while maintaining clarity.

✅ What You'll Learn in This Video:

The concept of post-order traversal on an N-ary tree.
How recursion handles multiple children efficiently and ensures proper traversal.
A step-by-step explanation of the recursive implementation in C#.
🔔 Highlights of This Solution:

Time Complexity: O(n), where n is the total number of nodes in the tree, as each node is visited once.
Space Complexity: O(h), where h is the height of the tree, due to the recursive stack.
Core Insight: The key concept is to process all the children of a node first and then visit the node itself, maintaining the left-to-right order of children.
💡 This problem is essential for understanding tree traversal with multiple children. Post-order traversal on N-ary trees is widely used in scenarios such as hierarchical data analysis, evaluation of expression trees, and file system-like operations.
