(c) The processing time of an algorithm is described by the following recurrence equation (c is a positive constant): T(n) = 3T(n/3) + 2cn; T(1) = 0 What is the running time complexity of this algorithm? Justify. (d) You decided to improve insertion sort by using binary search to find the position p where the new insertion should take place. (d.1) What is the worst-case complexity of your improved insertion sort if you take account of only the comparisons made by the binary search? Justify. (d.2) What is the worst-case complexity of your improved insertion sort if only swaps/inversions of the data values are taken into account? Justify.
