::: ''Create a function "s_of_n_creator" that given n, returns a function "s_of_n" that when called with successive items from a list returns an equi-weighted random sample of n elements from its arguments since creation using Knuths Algorithm S. Test your function by printing and showing the frequency of occurrences of the selected digits from 10000 repetitions of using the s_of_n_creator(3) and for each s_of_n using the last set of 3 elements when it is given the integers 0..9 inclusive.'' |
