Red-Black Tree definition & meaning in DSA
A red-black tree is a self-balancing binary search tree in which each node of the tree has an color, which can either be red or black.
Characteristics of Red Black Tree:
- The root node is always black and each node can be either black or red.
- Every leaf node of the red-black tree is black.
- The children of red nodes are black.
- The number of black nodes will be the same for every simple path from the root to the descendant leaf node.
Applications of Red Black Tree:
- Red-black trees are commonly used to implement ordered data structures like sets and maps.
- Red Black Trees are used in implementing the graph algorithms such as Prim’s minimum spanning tree algorithm and Dijkstra’s shortest path algorithm.
- Red-black trees are used in memory allocation algorithms to manage memory blocks efficiently.
- It is also used in the K-mean clustering algorithm in machine learning for reducing time complexity.

Advantages of Red Black Tree:
- The mechanism to maintain balance is relatively easy to understand.
- It performs operations like insertion, deletion, and searching in logarithmic time.
- It reduces the number of height comparisons and memory accesses needed hence improving performance.

Disadvantages of Red Black Tree:
- It has a more complicated implementation than standard binary search trees.
- Insertion and deletion operations may require complex restructuring of the tree.
- It is not as efficient as hash tables for small data sets.
