Throughout this assignment, adopt the following notation: a || B denotes the concatenation of lists a and B (in this order); e denotes the empty string; len(s) 20 denotes the length (number of characters) on string s; minx(A[a...b]) denotes the index (in range [a...b]) of the minimum odd element from list A[a...b); h = a +[(b-a)/3] and 12 = b-[(b-a)/3] denote the indices at one third and two thirds the way from a lo b, respectively; pairsort(X,Y) denotes either Y | X (if X and Y are both odd and X > Y) or X | Y (other- wise). Consider the problem of sorting the odd elements in a list of integers while keeping the even ones unchanged in their original places. Sort the odd elements in a list (ODDSORT) Input: A[1...n] a list of integers. Output: List A'[l...n] such that A'[i] = A[i] if A'[i] is even, and A'[i] = A'[j] for all Isis jsn such that A'[i] and A' [j] are both odd. 2. (2+2 points) Using the same reduction as in the previous question, now state a re- currence T(n) that expresses the worst case running time of the recursive algorithm assuming that minx() runs in linear time. Solve that recurrence and state the tight (Big Theta) bound on T(n). Hint: look for a similar recurrence in the course notes.
