5. Consider the Merge-Sort (MS) algorithm presented in class. Which pemutation of the input list (1, 2,3,4, 5,6,7, 8,9,10) will elicit the best-case perfomance (as measured in number of comparisons) between elements in the input list. We do NOT count comparisons to sentinels. (5 points) Also, answer the same question for worst-case. (5 points) The merging subroutine of MS in denoted by M. MS(A, p,r) Ifp
