Which data structure lets you store staff names as keys with their office room numbers as values for quick lookup?
Associative array (map/dictionary)
Two-dimensional array
String
Linked list
An associative array (often called a map, dictionary, or hash table) stores key-value pairs, allowing efficient retrieval of a value (room number) from its associated key (staff name). A two-dimensional or standard array lacks direct key lookup, a linked list requires linear search, and a string is not a container for multiple key-value pairs.
