Algorithms 101: Understanding Recursive Tree Operations
•
The Nature of Trees: Recursive Data Structures Trees are inherently recursive data structures. A tree is made of sub-trees, which in turn are made of other sub-trees, and ultimately, all these sub-trees form the same tree. Each node in a tree can be considered a tree itself because you can…
