WebStarting from a recurrence relation, we want to come up with a closed-form solution, and derive the run-time complexity from the solution. Remember that you have to prove your closed-form solution using induction. A slightly different approach is to derive an upper bound (instead of a closed-formula), and prove that upper bound using induction.
