WebbUse a recursion tree to determine a good asymptotic upper bound on the recurrence T (n) = 4T (n/2 +2)+n T ( n) = 4 T ( n / 2 + 2) + n. Use the substitution method to verify your answer. The recurrence T (n) = 4T (n/2+2)+ n T ( n) = 4 T ( n / 2 + 2) + n has the following recursion tree: Adding up the costs of each level of the tree: WebbConquering solves two subproblems, each on an array of n/2elements: 2T(n/2). Combining calls FIND-MAX-CROSSING-SUBARRAY, which takes Θ(n), and some constant tests: Θ(n) + Θ(1). T(n) = Θ(1) + 2T(n/2) + Θ(n) + Θ(1) = 2T(n/2) + Θ(n). The resulting recurrence is the same as for merge sort: So how do we solve these? hendaye legarralde
