Red-Black Trees

Introduction

Red-Black Trees are a type of self-balancing binary search tree. They ensure that the tree remains balanced, leading to efficient operations such as insertion, deletion, and searching.

Things to Remember

• Red-Black Trees follow certain properties to maintain balance:
• Every node is either red or black.
• The root node is always black.
• Red nodes cannot have red children (no two consecutive red nodes).
• Every path from a node to its descendant null nodes must have the same number of black nodes.
