Like the AVL tree, the Red-Black tree is also a self-balancing binary search tree. We learned that inserting or removing a node from the AVL tree might cause rotations, so if we need a self-balancing tree that involves many frequent insertions or deletions, then the Red-Black tree is preferred. If the insertions and deletions are less frequent (we are interest in frequent search operations), then the AVL tree is preferred over the Red-Black tree.
In the Red-Black tree, every node follows the rules which are listed as follows:
- As the name of the tree suggests, each node is either red or black.
- The root of the tree is black.
- All of the leaves are black (nodes represented with the NULL reference).
- If a node is red, then both ...
