Identify asymptotic tight-bounds (with notation) for T (n) in each of the following recurrences. Assume that T (n) is constant for small n if not specified otherwise. If you use the substitution method or the recursion-tree method, always remember to prove the correctness of your guess. a. (3 points) T (n) = T (n 1) + 3, T (0) = 1 b. (3 points) T (n) = 3T (n/2) + n2 c. (3 points) T (n) = 3T (n/3) + n log n
