Red-Black Trees

Red-Black Trees are self-balancing binary search trees that keep operations efficient by maintaining a roughly balanced structure.

Why They Are Useful

These trees help keep search,insert, and deletion operations efficient.Because the tree stays balanced, these operations usually take O(log n) time.

Important Properties

• Each node is either red or black.
• The root is always black.
• No red node can have a red child.
• The black height of the tree should be the same in all subtrees from the root to the null nodes.
• Null nodes are black.

How Balance is Maintained

After insertion or deletion,rotations and recoloring algorithms are used to restore the Red-Black Tree properties.
