This question concerns the following sorting algorithm (attachment). (b) Consider the operation of SORT on a list of length N. How many comparisons in line 4 take place when i = 1 and when i = N-1? (c) How many comparisons take place in total? Show your working. You may use the result 1+2+...+n=n[(n+1)/2] (d) Based on the analysis above, or otherwise, what is the worst, best and average- case time
