Generally, a method that uses exponential recursion is often very easy to replace with a more efficient iterative solution.

Question

Quizplus · Accepted Answer

Exponential recursion often indicates that the method is solving the same subproblems multiple times, which can lead to inefficiency. While it's possible to optimize recursion using techniques like memoization, replacing it with an iterative solution might not be straightforward and requires a different approach to avoid the exponential time complexity, such as dynamic programming.
