How do you build a red-black tree?

Answer 1

To build a red-black tree, you start with an empty tree and insert nodes one by one, following the standard binary search tree insertion rules. After each insertion, you perform rotations and recolor the nodes as necessary to maintain the red-black properties: each node is either red or black, the root is always black, red nodes cannot have red children, and every path from a node to its descendant leaves must have the same number of black nodes. After inserting all nodes, you ensure that these properties are preserved through appropriate adjustments. Overall, the process combines binary search tree insertion with specific balancing operations to ensure the tree remains balanced.
