Q3) 54 def recursiveDigits(digitStr): The parameter digitStr is a string containing at least one positive digit. The function reverses the digits using recursion. Return a string that contains the reversed number. 3A) What is the base case for recursiveDigits? Write down this base case in terms of the 'if statement and its corresponding action that will be inside the 'if block in the function. 3B) Express an example of the next simplest case (a case that occurs immediately after the base case) as the additional action that you need to take together with the specific function call to the recursiveDigits that immediately goes to the base case. Note that you should not be using the digitsta parameter in this part of your answer, since we are asking you for a specific action and a specific function call that will produce the correct output for a specific example of the next simplest case, 3C) Generalize your answer to 3B to write the 'else block of this recursive function, Note that this is where you should be using the given parameter, since this is part of the recursive step
