accumulate
Syntax:
#include <numeric> TYPE accumulate( iterator start, iterator end, TYPE val ); TYPE accumulate( iterator start, iterator end, TYPE val, BinaryFunction f );
The accumulate function computes the sum of val and all of the elements in
the range [start,end).
If the binary function f if specified, it is used instead of the + operator to
perform the summation.
accumulate runs in linear time.
