Understanding Parent, Grandparent, and Uncle in Red-Black Trees (With Example)

by

Red-Black Trees are powerful self-balancing binary search trees used in many system-level and database applications. When inserting or deleting nodes, specific relationships between nodes—such as parent, grandparent, and uncle—become crucial in maintaining the tree’s balanced structure. In this article, we’ll break down these relationships, explain their significance during tree adjustments, and provide easy-to-understand examples. Whether … Read more

Insertion in Red-Black Tree: All Cases Explained with Algorithm

by

Red-Black Tree is a self-balancing binary search tree. When a node is inserted, the structure of the tree may violate some of its coloring properties. Therefore, we need to fix those violations using recoloring and rotations to maintain balance. Let’s explore how insertion works in a Red-Black Tree — step-by-step — including all the violation … Read more

Rotations in Red-Black Tree

by

Balancing a binary search tree is crucial to ensuring efficient performance. One of the most powerful self-balancing binary search trees is the Red-Black Tree (RBT), widely used in memory management, language libraries (like C++ STL map and set), and database indexing. But what keeps this tree balanced? The secret lies in rotations – a fundamental … Read more

Red-Black Tree: Definition, Example, Advantages and Disadvantage

by

A Red-Black Tree is a type of self-balancing binary search tree where each node has a color — either red or black. It follows specific rules related to these colors to keep the tree balanced after every insertion or deletion. This balance helps in keeping operations like search, insert, and delete efficient, taking only O(log … Read more
