WebInsertion sort is a stable sorting algorithm. We can optimize insertion sort further using binary search. Insertion sort is a more efficient sorting algorithm than selection and bubble sort. The average case time complexity of the insertion sort is closer to the worst-case time complexity, i.e. O (n²).

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.
