cpp map

What is a cpp map? C++ map is an associative container that is used to store and sort elements in an orderly fashion. C++ map stores information in <key, value> pairs and we can access the value field from the key in O(logn) time. Using the map, you can effortlessly search for elements based on their keys. Keys and values are essential to a C++ map.

Cpp map is a container that stores elements in key-value pairs. It's similar to collections in Java, associative arrays in PHP, or objects in JavaScript.  map only stores unique keys, and the keys themselves are in sorted order; Because the keys are already in order, searching for an element is very fast; There is only one value for every key.
