Instance Method

# shuffled()

Returns the elements of the sequence, shuffled.

## Return Value

A shuffled array of this sequence’s elements.

## Discussion

For example, you can shuffle the numbers between 0 and 9 by calling the shuffled() method on that range:

This method is equivalent to calling shuffled(using:), passing in the system’s default random generator.

Complexity: O(n), where n is the length of the sequence.
