The overhead associated with iterative methods is greater in terms of both memory space and computer time compared to the overhead associated with executing recursive methods.

The overhead associated with executing recursive methods is greater in terms of both memory space and computer time compared to iterative methods. This is because recursive methods need to store each function call on the memory stack, which can lead to a stack overflow error if there are too many recursive calls. Iterative methods, on the other hand, do not require the use of a memory stack and can be more efficient.
