template< class SinglePassRange, class OutputIterator > OutputIterator adjacent_difference( const SinglePassRange& source_rng, OutputIterator out_it); template< class SinglePassRange, class OutputIterator, class BinaryOperation > OutputIterator adjacent_difference( const SinglePassRange& source_rng, OutputIterator out_it, BinaryOperation op);
            adjacent_difference calculates
            the differences of adjacent_elements in rng.
          
            The first version of adjacent_difference
            uses operator-()
            to calculate the differences. The second version uses BinaryOperation
            instead of operator-().

              x and y are objects of SinglePassRange's value type, then
                x -
                y is defined.

            Linear. If empty(rng)
            then zero applications, otherwise distance(rng) - 1
            applications are performed.
