Question 1: Algorithms

August 2013



Question

Part 1. /item Assume the run time for some algorithm is given by the following recurrence: $ \begin{equation} T(n) = 2T(\sqrt[]{n}) + \log n \end{equation} $ Find the asymptotic run time complexity of this algorithm. Give detail of your computation.

Assume functions $f$ and $g$ such that $f(n)$ is $O(g(n))$. Prove or disprove that $3^{f(n)}$ is $O(3^{g(n)})$.
