Which tree data structure is used by map?

HashMap and LinkedHashMap use array data structure to store nodes but the TreeMap uses a data structure called Red-Black tree. Also, all its elements store in the TreeMap are sorted by key. TreeMap performs sorting in natural order on its key, it also allows you to use Comparator for custom sorting implementation.

Which data structure is used by map in C++?

Introduction to map Map is dictionary like data structure. It is a sequence of (key, value) pair, where only single value is associated with each unique key. It is often referred as associative array.

A HashMap is a data structure that is able to map certain keys to certain values. The keys and values could be anything.

What is a map data structure?

What type of data is a map?

Fundamentally, maps display only two types of data: qualitative and quantitative. Qualitative data differentiates between various types of things. Quantitative data communicates a message of magnitude.
