WebThis cannot be solved by the Master Theorem. However, it can be solved using the recursion tree method to resolve to O (n log log n). The intuition behind this is to notice that at each level of the tree, you're doing n work. The top level does n work explicitly. Each of the √n subproblems does √n work for a net total of n work, etc. WebApr 1, 2024 · There are three methods used to analyse recurrence relations: Substitution Method: Using mathematical induction to prove an assumed solution.
