Solve the following recurrence relations. If possible, use the Master Theorem. If the Master Theorem is not possible, explain why not and solve it using another approach (substitution with n = 3h or h - log3(n).

a. T(n) = 7 * n2 + 11 * T(n/3)

b. T(n) = 4 * n3 * log(n) + 27 * T(n/3)

Solve the following recurrences: (a) T(n) = T(n=2) + O(n), with T(1) = 1. Solve this two times: one with the substitution method and one with the master theorem from CLRS. When you use the master theorem, carefully show the values for the parameters a; b. For the following cases you can use your preferred method. In either case, show your work: (b) T(n) = 2T(n/2) + O(1), T(1) = 1. (c) T(n) = 3T(n/2) + O(1), T(1) = 1....
