The term "leaf node" can refer to two different contexts: one in botany (the study of plants) and the other in computer science (specifically in data structures). Let’s break them down.
Definition: A "leaf node" is a part of a plant stem where one or more leaves grow. It is the small swelling or bump on the stem that supports the leaves.
Definition: A "leaf node" is a term used in data structures, particularly trees. It refers to a node that does not have any children, meaning it is at the end of a branch.
While "leaf node" does not have common idioms or phrasal verbs, the word "leaf" can appear in idioms, such as "turn over a new leaf," which means to change one’s behavior for the better.
Understanding "leaf node" depends on the context. In botany, it refers to the part of a plant where leaves grow, while in computer science, it denotes a terminal point in a tree structure.
