Overview of Trees

Explore various types of tree data structures such as binary trees, binary search trees, red-black trees, AVL trees, and 2-3 trees. Understand their key characteristics, node counts, heights, and balancing properties to build a solid foundation for coding interviews.

Binary trees

Definition: A tree where each vertex has two children at most.

Types: Perfect, Full, Complete, and 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 ...
