WebMay 21, 2024 · A recursive solution is only as efficient as the equivalent iterative solution if the compiler/interpreter is smart enough to unroll it into an iterative solution. I'd love to be corrected, but I don't believe the Python interpreter is able to unroll recursive algorithms such as this one. If that is so, an iterative solution will be more efficient.

WebJul 15, 2015 · Recursion is a way of programming or coding a problem, in which a function calls itself one or more times in its body. Usually, it is returning the return value of this function call. If a function definition fulfils the condition of recursion, we call this function a recursive function.
