red-black trees
Red-black trees are a type of self-balancing binary search tree. They ensure that the tree remains roughly balanced, reducing the time complexity of various operations such as search, insertion, and deletion to O(log n), where n is the number of elements in the tree. The "red" and "black" in their name refer to the colors assigned to each node, which help maintain the balanced structure. By following specific rules regarding color and structure, red-black trees enable efficient and reliable tree operations.
