Q5 (25pts) Consider the code: int foo(int N){ if (N <= 3) return 2; int res1 = 3*foo(N-4); int res2 = foo(N-2); return res1-res2; } a) (6 points) Write the recurrence formula for the time complexity of this function (including the base cases) for N>=0. You do NOT need to solve it. b) (5 points) Draw the tree that shows the function calls performed in order to compute foo(8) (the root will be foo(8) and it will have a child...
