Properties of red- black tree, Data Structure & Algorithms

Assignment Help:

Any Binary search tree has to contain following properties to be called as a red- black tree.

1. Each node of a tree must be either red or black.

2. The root node is always black.

3. If a node is red then its children must be black.

4. For every node, all the paths from a node to its leaves have the same number of black nodes.
