Discussion
Which of the following is an ordered collection of elements of the same type?
Answer: C
Correct answer: List
A list is ordered and typed: its elements have positions, so the same value may appear more than once and the order is part of the collection’s identity. A set is unordered and rejects duplicates, a bag is unordered but allows them, and a dictionary is a collection of key-value pairs rather than of elements of one type. Ordering is the property that separates the list from all three.
