Maps (also known as Dictionaries) are data structures stores a collection of key-value pairs. Each key is unique and allows for quick access to values. A real life example of a map could be storing the grades for students in a class (student name is key, grade is value).
The map data structure is typically implemented as an associative array or hash table, with each key-value pair assigned a unique index using a hash function. The value associated with that key is then stored and retrieved using this index.
The map data type is known as an associative array because, like an array, it is a collection of values and not a single value like an Int or a String. Also, each unique key is associated with a value, making it an associative array.
Types of Maps in Data Structures
There are several different types of maps or dictionary data structures used in computer science and data Map Data Structure in Different Languages
1. Maps in C++
Maps areassociative containers that store elements in a mapped fashion. Each element has a key value and a mapped value Internal Implementation of Map Data Structure
The Map data structure is a collection of key-value pairs that allows fast access to the values based on their corresponding keys Ordered vs Unordered Map in C++
1. Ordered Map
In C++ Operations Associated with Map Data Structures
A map is a data structure that allows you to store key-value pairs. Here are some common operations that you can perform with a map: 1 Properties of Map Data Structure
Here are some of the properties of the map data structure: 1. Uniqueness: The keys in a map are unique, meaning that each key can only map to one value Applications of Map Data Structure
1. Indexing and retrieval:Maps are used to index elements in an array and retrieve elements based on their keys. 2
