`std::sort` does not perserve the order of elements within equal values, however the result of it is of no randomness.

A demo show for parallem_sum of hyper_sum by using of std::async.
#include <iostream>
#include <future>
template <typename IntT, typename UnaryFunc>
IntT do_hyper_sum(const IntT begin, const IntT end, const UnaryFunc func) {
IntT res = 0;
for (IntT i = begin; i != end; ++i) {
res += func(i);
}
return std::move(res);
