Evaluation Recursion: is your function recursive? Test code: did you apply separation of concerns and design for reuse? Syntax and logic errors. . Description Develop a Python solution to the following problems. 1. Change the palChecker function (in the palindrome_checker.py file) as follows. a. Remove use of the Deque. b. Rewrite the palChecker function so it is recursive. Important: Your new palChecker function should NOT have any loop statement in it! 2. In your source code file, add test code to test your modifications to the palChecker function. a. . Think about the test cases you need to implement for each modification you made. b. Be sure to apply separation of concerns and design for reuse when developing your test code. from pythonds.basic import Deque def palchecker(aString): chardeque = Deque() for ch in aString: if ch.isalpha(): chardeque. addRear(ch.lower()) stillEqual = True while chardeque.size() > 1 and stillEqual: first = chardeque. removeFront() last = chardeque.removeRear() if first != last: stillEqual = False = return stillEqual print(palChecker(\"lsdkjfskf\")) print(palchecker(\"radar\")) print(palChecker(\"A man, a plan, a canal, panama.\")) , ,
