Overview of Trees

Learn the definitions and characteristics of common tree types such as binary trees, binary search trees, red black trees, AVL trees, and 2-3 trees. Understand their node counts, height properties, and balancing conditions to effectively implement them in Java.

Binary Trees

Definition: A tree having a max. of two children at each internal node

Types: Perfect, Full, Complete, Skewed

Total number of nodes: 2(h+1)12^{(h+1)}-1

Total number of leaf nodes: 2hor(n+1)22^{h} or \frac{(n+1)}{2}

Height: log2(n+1)1log_{2}(n+1)-1 ...
