random_shuffle (RandomAccessIterator first, RandomAccessIterator last) Function

void random_shuffle(RandomAccessIterator first, RandomAccessIterator last,
                    RandomNumberGenerator& rand);

random_shuffle shuffles the elements in the range [first, last) with uniform distribution. Exactly (last - first) - 1 swaps are done. random_shuffle can take a particular random number generating function object rand such that rand takes a positive argument n of distance type of the RandomAccessIterator and returns a randomly chosen value between 0 and n-1.
