std::unordered_map is implemented using the hash table in C++. Hash tables also belong to associative containers. The mapped values are stored in a hash table in an array of buckets or slots, from which necessary values can be retrieved. This indexing is done using the hash function, hash...

However, they are implemented using hash tables. The element, also called a key, to be inserted is hashed into an index of the hash table and gets stored at that particular index. Since the elements are stored in any random order, retrieving them takes O(1) time, making its search ...
