1,2) Finds an element with key equivalent to key. If there are several elements with key in the container, any of them may be returned.
3,4) Finds an element with key that compares equivalent to the value x. This overload only participates in overload resolution if the qualified-id Compare::is_transparent is valid and denotes a type. It allows calling this function without constructing an instance of Key
key - key value of the element to search for
x - a value of any type that can be transparently compared with a key
Iterator to an element with key equivalent to key. If no such element is found, past-the-end (see end()) iterator is returned.
Logarithmic in the size of the container.
