Description: A multimap is a type of associative container in C++ that allows multiple values to be associated with a single key. Unlike a standard map, where each key is unique and associated with a single value, a multimap allows the same key to be linked to multiple values. This makes it a useful tool for situations where collections of data may share the same key, such as in various data management scenarios where multiple entries may need to be recorded under the same identifier. Multimaps are part of the C++ standard library and are implemented as balanced trees, ensuring that insertion, search, and deletion operations are performed in logarithmic time. Additionally, multimaps allow iteration over their elements in order, making it easy to retrieve data in an ordered format. Their flexibility and efficiency make them ideal for applications requiring dynamic handling of associated data, such as databases, information management systems, and data analysis applications.
