Assume that your computer has special hardware that finds the minimum of k (or fewer) elements in one comparison step. Your answers to this question should have n and k as parameters. (a) Design (in English) an efficient algorithm based on Merge sort to sort n elements using this special hardware. (This is an upper bound.) (b) Analyze your algorithm. Get the higher order term exactly. (c) Use decision trees (no need to draw) to find a lower bound for sorting when using this special hardware. (d) Compare your upper and lower bounds
