Part B: Shuffling (7) Write a function triple_riffle (mylist) which takes as input a list (which for convenience we will always take with length a multiple of 3) and outputs the result of a 3-way riffle shuffle as described i the lecture notes. For example: an input of range (9) should output [6, 3, 0, 7, 4, 1, 8, 5, 2]. (8) Write a function triple_riffle_repeat (mylist, n) which takes as input a list (again with length a multiple of 3) and outputs the result of doing a 3-way riffle shuffle n times. (9) Write a function period (m) which takes as input a number m (which we will always take as a multiple of 3) and outputs the smallest positive integer n so that triple_riffle_repeat (list (range (m)), n) list (range (m)). (10) Discuss, with evidence, the outputs of your function period for different values of m, writing your answer as a comment.
