Red-Black Trees

What is a Red-Black Tree?

A red-black tree is a binary search tree that keeps itself balanced. Each node is colored either red or black, which helps the tree stay balanced as elements are added or removed.

Why Are They Useful?

Red-black trees are useful because they keep operations fast. Searching, inserting, and deleting elements are all O(log(n)).

• They prevent the tree from becoming too tall
• They are fast
• They are used in real systems like databases and libraries
