WebbIf recurrence is in the form of T (n) = aT (n/b) + f (n) then the depth of the tree is log base b of n. For example, 2T (n/2) + n recurrence would have tree of depth lg (n) (log base 2 of n).

Multiplying large Integers Problem. At each successive level of recursion the sub problems get halved in size. At the (log 2 n)th level, the sub problems get down to size 1, and so the; recursion ends.

Webb15 feb. 2024 · This theorem is an advance version of master theorem that can be used to determine running time of divide and conquer algorithms if the recurrence is of the following form :-. where n = size of the problem. a = number of subproblems in the recursion and a >= 1. n/b = size of each subproblem. b > 1, k >= 0 and p is a real number. Webb22 mars 2024 · T (n) = 7T (n/2) + 3n^2 + 2 As one can see from the formula above: a = 7, b = 2, and f (n) = 3n^2 + 2 So, f (n) = O (n^c), where c = 2. It falls in master’s theorem case 1: logb (a) = log2 (7) = 2.81 > 2 It follows from the first case of the master theorem that T (n) = θ (n^2.8) and implies O (n^2.8) as well as O (n^3). fiber in 1 cup lentils
