randomShuffle(BidirectionalIterator, BidirectionalIterator)

Shuffle a sequence with uniform distribution by performing as many random swaps as there are elements.

randomShuffle(Container)

Shuffle a random access container with uniform distribution by performing as many random swaps as there are elements.

setSeed(long)

Set the seed which will be use for shuffling.

 public static void randomShuffle(BidirectionalIterator first,
                                  BidirectionalIterator last)

Parameters:

first - An iterator positioned at the first element of the sequence.

last - An iterator positioned immediately after the last element of the sequence.

 public static void randomShuffle(Container container)

Parameters:

container - The container.

 public static void setSeed(long seed)

Set the seed which will be use for shuffling.

Parameters:

seed - the seed to be set
