Question: 1 / 400

What type of set does a map represent in a set of name-value pairs?

Ordered

Unordered

A map in a programming context represents a collection of name-value pairs where each value is associated with a unique key. The key characteristic of a map is that it is unordered. This means that the elements are not stored in any particular order and do not maintain the order in which the name-value pairs are inserted.

In programming languages, when you use a map, you can retrieve values based on their key without concern for the sequence of those pairs. This distinguishes maps from ordered collections, like lists or arrays, where the order of elements matters and is preserved.

Being unordered allows maps to provide efficient lookups, inserts, and deletes based on keys, which is vital for many applications that require fast access to associated data. Therefore, the function and structure of a map align precisely with the definition of an unordered set.
