partial_sum

template<class InIt, class OutIt>

OutIt partial_sum(InIt first, InIt last,

OutIt result);

template<class InIt, class OutIt, class Fn2>

OutIt partial_sum(InIt first, InIt last,

OutIt result, Fn2 func);

The first template function stores successive values beginning at result, for each value of the

InIt iterator I in the interval [first, last). The first value val stored (if any) is *I.

Each subsequent value val stored is val + *I. The function returns result incremented

last - first times.

The second template function stores successive values beginning at result, for each value of

the InIt iterator I in the interval [first, last). The first value val stored (if any) is

*I. Each subsequent value val stored is func(val, *I). The function returns result

incremented last - first times.
