We now … WebbInduction step For n > 0, T(n) = T(floor(n/2) + n <= 2 floor(n/2) + n <= 2(n/2) + n = 2n. We might be able to prove a slightly tighter bound with more work, but this is enough to sho T(n) = O(n). Showing that T(n) = Omega(n) is trivial (since T(n) >= n), so we get T(n) = Θ(n) and we are done. sendinblue hubspot integrationWebb12 maj 2016 · 2.

Webb2 Answers Sorted by: 1 Your induction hypothesis is that I ( n) = n + 1. The base case is true by the first line of the function. Assume it is true for all integers < n. If n = 2 k then it is true by the last line of the function. Else n = 2 k + 1 so n + 1 = 2 ( k + 1), k = ⌊ n / 2 ⌋. WebbIn this module, we study recursive algorithms and related concepts.
