    In red-black trees, the leaf nodes are not relevant and do not contain data. A red black tree is a balanced binary search tree. In this tree every node is colored either red or black. Same as extended binary, it’s all null links are replaced with special nodes (external nodes) and there is no key value or does not contain any data.

    Properties of red black tree.
    • Root node is always black.
    • All external nodes are black.
    • Black node can have red or black children.
    • A red node cannot have red children.
    Red black tree
