1. Given a set of numbers: A = {3, 41, 52, 26, 38, 57, 9, 49}. a) Use merge-sort to sort the array. Show each step. b) Use quick-sort to sort the array. Show each step. c) How many "comparisons” for each algorithm above? 2. Use binary-search for finding the number 38 for the sorted array based on Question 1, show each step. 3. The time complexity equation of merger-sort is T(n) = 2* T(n/2) + n, where T(1) = C and C is a constant. Solve this equation by giving detailed steps. (Hint: See lecture notes) If you have an equation like the following T(n) = 3* T(n/3) + n, where T(1)=T(2)=C, what would be T(n)?
