In this section we will see what is the Red-Black Tree. The Red-Black Trees are self-balancing binary search tree. There are some conditions for each node. These are like below −
Each node has color. Which is either Red or Black
The root will be always black
There will be no two adjacent Red nodes
Every path from a node (including root) to any of its descendent NULL node has the same number of black nodes.
AVL Trees are more balanced than the Red-Black tree. But the major disadvantage is, there will be more rotations during insertion and deletion. For multiple insertion and deletion, Red-Black tree will be helpful.
