Leaf Node
Domain: Data Structures
🎯 Motivation
A leaf node is a tree node with no children. It represents the end of a branch.
📋 Concrete Example
In a file system, individual files are leaves — they contain data but have nothing nested inside them. Folders with only files are also effectively leaves.
🔗 Analogy
The tip of a tree branch where a leaf grows. Nothing branches off from there — it is an endpoint.
