stdhashKey
stdhashKey is a concept related to hash tables and their implementation in programming. In the context of C++'s Standard Template Library (STL), `std::hash` is a function object that provides a default hash function for various data types. When using containers like `std::unordered_map` or `std::unordered_set`, the `std::hash` object is used to compute hash values for the keys.
The `stdhashKey` itself is not a specific class or function, but rather refers to the underlying mechanism
A well-defined hash function is crucial for the efficient operation of hash tables. It should distribute keys
For custom data types to be used as keys in STL hash-based containers, it is necessary to
