Can Recursive Function Return Value?

4 Answers. The recursive calls of the function do not influence on the returned value. Only the first return met in the first instance of your recursive function will return a value to the parent function. Any other return met will just stop the function's instance the program is currently in.

How do you return a recursive function?

You don't "break" out of recursive functions. Trying to do so says you're thinking about them the wrong way. Currently your recursive call is ignoring the output, which means that the recursion is pointless; whatever is_pal(middle(str)) returns has no effect on the return value of your function.

Can a recursive function return multiple values?

This allows your actual recursive function to have more than 1 argument. You can't return two values separately. You can, however, return an array containing the first bit and the last bit or create your own class to hold this data, and return an instance of that class.
