A 2-3 tree is never taller than a minimum-height binary tree.

Question

Quizplus · Accepted Answer

A 2-3 tree is a type of self-balancing tree that can have either one or two data values per node. The minimum-height binary tree is a binary tree where all the leaves are at the same level. In a 2-3 tree, every node must have at least one data value, so it is impossible for there to be a level in the tree with no nodes. Therefore, the height of a 2-3 tree is always less than or equal to the minimum-height binary tree.
