template function find_fn::operator()

range-based version of the find std algorithm

Precondition

Rng is a model of the Range concept

I is a model of the InputIterator concept

S is a model of the Sentinel<I> concept

P is a model of the Invocable<iter_common_reference_t<I>> concept

The ResultType of P is EqualityComparable with V

operator()() [2/2]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
