An input iterator that indicates the end of a range.
The condition to test for. This is provided by a user-defined predicate function object that defines the condition to be satisfied by the element being searched for. A predicate takes a single argument and returns trueor false.
The template function returns true only if all elements in [_First, _Last) are partitioned by _Comp; that is, all elements X in [_First, _Last) for which _Comp(X) is true occur before all elements Y for which _Comp(Y) is false.
