Hash pair
WebA hash is a data structure used to store data in the form of UNIQUE key-value pairs. Unlike arrays, there are no numerical indexes, you access the hash values with keys. Examples include: A list of country names & their corresponding country codes (like ES ⇾ Spain) A dictionary, where every word has a list of possible definitions WebC++ doesn't supply a std::hash<...>>, so I decided to implement one.However, I was viewing this as more of a hash library than extensions to std, so I placed it all under the namespace utils..
