    p - binary predicate which returns ​true if the elements should be treated as equal.

    The signature of the predicate function should be equivalent to the following:

    bool pred(const Type1 &a, const Type2 &b);

    The signature does not need to have const &, but the function must not modify the objects passed to it.
    The types Type1 and Type2 must be such that objects of types ForwardIt1 and ForwardIt2 can be dereferenced and then implicitly converted to Type1 and Type2 respectively.

    ​

    Type requirements
    -
    ForwardIt1, ForwardIt2 must meet the requirements of ForwardIterator.
