WebApr 30, 2024 · Fix the broken red-black-tree-property by rotations and coloring. Since the new node is red, we can violate the red-black-tree-property – if a node is red, then both of its children are black, and we can fix the violation after the insertion. We can implement the red-black tree insertion in a similar way to the normal binary search tree ...

There are two types of rotations: 1. Left Rotation 2. Right Rotation In left rotation, we assume that the right child is not null. Similarly, in the right rotation, we assume that the left child is not null. Consider the following tree: After applying left rotation on the node x, the node y will become the new root of the subtree and its … See more We insert a new node to a red-black tree in a similar way as we do in a normal binary search tree.
