What is a self-balancing binary search tree?

A self-balancing binary search tree is a type of binary search tree that automatically adjusts its structure to maintain a balanced state. This means that the heights of the left and right subtrees of any node differ by at most one. Self-balancing binary search trees use various algorithms, such as AVL trees, red-black trees, or splay trees, to ensure efficient operations like insertion, deletion, and search, with a guaranteed worst-case time complexity of O(log n).
