random_selection chooses n items at random from a random access iterator range which is useful to produce degenerate input data sets with multiple entries of identical items.

#include <CGAL/random_selection.h>

template <class RandomAccessIterator, class Size, class OutputIterator, class Random>
random_selection ( RandomAccessIterator first,
RandomAccessIterator last,
Size n,
OutputIterator result,
Random& rnd = default_random)
chooses a random item from the range [first,last) and writes it to result, each item from the range with equal probability, and repeats this n times, thus writing n items to result. A single random number is needed from rnd for each item. Returns the value of result after inserting the n items.
Precondition: Random is a random number generator type as provided by the STL or by Random.
