The complexity of an algorithm describes the total amount of time it takes to run.

The case complexity of an algorithm refers to the expected amount of time it takes to execute for inputs of typical size.

The worst case complexity of an algorithm refers to the amount of time it can take to execute.

The complexity of an algorithm describes the total amount of memory space it requires.

In the context of complexity analysis, the term case refers to the scenario in which the algorithm performs exceptionally well.

The best case complexity is often used to describe the best possible of an algorithm under certain conditions.

The average case complexity is useful for understanding how the algorithm is likely to perform on inputs.

An algorithm's efficiency can be measured by its complexity and its space complexity.

The case complexity gives us an idea of how the algorithm performs on inputs that are representative of real-world scenarios.
