Defined in header <experimental/algorithm>
template< class RandomIt> void shuffle( RandomIt first, RandomIt last);		(library fundamentals TS v2)

Reorders the elements in the given range [first, last) such that each possible permutation of those elements has equal probability of appearance, using the per-thread random number engine as the random number generator.

Parameters

first, last	-	the range of elements to shuffle randomly
- RandomIt must meet the requirements of ValueSwappable and RandomAccessIterator.

Return value

(none)

Complexity

Linear in the distance between first and last.
