WebThe leaves of the recursion tree will always return 1. The value of Fib (n) is sum of all values returned by the leaves in the recursion tree which is equal to the count of leaves. Since each leaf will take O (1) to compute, T (n) is equal to Fib (n) x O (1). Consequently, the tight bound for this function is the Fibonacci sequence itself (~ θ ... WebAug 23, 2013 · 3. Each function call does exactly one addition, or returns 1. The base cases only return the value one, so the total number of additions is fib (n)-1. The total number of function calls is therefore 2*fib (n)-1, so the time complexity is Θ (fib (N)) = Θ (phi^N), which is bounded by O (2^N).
