LLRB maintains 1-1 correspondence with 2–3 trees

LLRB maintains 1-1 correspondence with 2–3 trees.
A. True
B. False

Answer:
A. True

Explanation:
LLRB (Left Leaning Red Black tree)is the data structure which is used to implement the 2-3 tree with very basic code. The LLRB is like the 2-3 tree where each node has one key and two links. In LLRB the 3-node is implemented as two 2-nodes connected by the red link that leans left. Thus, LLRB maintains 1-1 correspondence with 2–3 tree.
