Identify the correct rotation to balance the red-black tree.

Question

BlackTom AI · Accepted Answer

The provided data for this question is incomplete, which makes it impossible to perform a proper analysis of rotations for balancing a red-black tree.

First, I would need the actual list of answer options (A, B, C, D or similar) to compare the proposed rotations and determine which one achieves balance.

Second, I would need to know the specific state of the red-black tree before the rotation(s) in question. Red-black trees rely on the color properties (red vs black) and the binary search tree structure; the correct rotation depends on the local subtree configuration (e.g., whether a red-red violation occurs, the position of the newly inserted node, etc.).

Third, if there are multiple-step rotations (double rotations) required to restore balance, the exact sequence must be provided in the options so I can evaluate each candidate and justify which sequence yields a valid red-black tree after the operation.

Fourth, if the question follows a particular convention (e.g., labeling of rotations as LL, LR, RL, RR or as specific single/double rotations), I would need that convention to map the options to the corresponding operations.

In summary, without the answer choices and the initial tree state, I cannot determine which rotation is correct. To proceed, please supply:
- The complete set of answer options (the possible rotations).
- The specific subtree configuration and any insertions or deletions that led to the need for rotation.
- Any naming convention used for the rotations in this question (e.g., LL/RR/LR/RL or single/double rotation labels).

Once that information is provided, I will walk through each option, explain why it would or would not balance the tree, and highlight the reasoning for the correct choice while clearly identifying why the others are incorrect.
