Question
In a height-balanced tree, what is the minimum height of a leaf node?
a) It depends on the number of elements in the tree.
b) 1
c) -1
d) 0
Solution
The minimum height of a leaf node in a height-balanced tree is 0. So, the correct answer is d) 0.
Here's why:
In computer science, the height of a node in a tree is the number of edges on the longest downward path between that node and a leaf. By definition, the height of a leaf node is always 0 because there are no further downward paths from a leaf.
A height-balanced tree, also known as an AVL tree, is a type of binary search tree where for every node, the heights of the left and right subtrees differ by at most one. This property doesn't change the fact that the height of a leaf node is 0.
