Define best case, average case and worst case for analyzing the complexity of aprogram

Best Case: This is the scenario where the algorithm performs at its best. It means the input is in such a state that the algorithm doesn't need to work as hard as it normally would. For example, if you have a sorting algorithm and your input is an already sorted list, the algorithm will have less work to do, resulting in a best case scenario.

Average Case: This is the scenario where the performance of an algorithm is averaged out over all possible inputs. It provides a broad view of how the algorithm will perform in the "general" case, not considering the best or worst possible inputs. This is often the most practical analysis, as it considers both the high and low ends of performance.

Worst Case: This is the scenario where the algorithm performs at its worst. It means the input is in such a state that the algorithm has to do the most amount of work. For example, if you have a sorting algorithm and your input is a list sorted in reverse order, the algorithm will have to do the most work, resulting in a worst case scenario.

These cases are used to analyze the complexity of a program, which is a measure of the amount of time and/or space required by an algorithm for an input of a given size.
