WebMar 21, 2024 · In the context of a Red-Black Tree, a Rotation involves swapping the position of two nodes (a parent and one of its children) while maintaining the Binary Search Tree Properties. There are two kinds of rotation: Right Rotation: The left child is moved into the position of its parent and the former parent becomes the new parent's right child. WebMar 25, 2014 · What's the maximum number of rotations required after K insertions and K deletions in a Red Black tree?
