sample
Returns n elements sampled uniformly at random without replacement.
Each element position of this collection is used at most once, so the result has no repeated positions; repeated values can still appear when the source itself contains duplicates. Every subset of size n is equally likely. The relative order of the result is randomized.
Parameters
n
the number of elements to sample, must be within 0..size.
random
the source of randomness, Random.Default by default.
Throws
if n is negative or greater than the collection size.
