    Costruisce una std::seed_seq con la sequenza di seme iniziale ottenuto mediante iterazione sulla [begin, end) gamma e la copia dei valori ottenuti dalla dereferenziazione l'iteratore, modulo 232
     (cioè i bit inferiori 32 sono copiati)
    Original:
    Constructs a std::seed_seq with the initial seed sequence obtained by iterating over the range [begin, end) and copying the values obtained by dereferencing the iterator, modulo 232
     (that is, the lower 32 bits are copied)

#include <sstream>
#include <iterator>
int main()
{
    std::seed_seq s1; // default-constructible
    std::seed_seq s2{1, 2, 3}; // can use list-initialization
    std::seed_seq s3 = {-1, 0, 1}; // another form of list-initialization
    int a[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    std::seed_seq s4(a, a + 10); // can use iterators
    std::istringstream buf("1 2 3 4 5"); 
    std::istream_iterator<int> beg(buf), end;
