Calling a recursive function.   Write a statement that calls the recursive function backwards_alphabet() with input starting_letter. Sample output with input: 'f' f  e d c b a def backwards_alphabet(curr_letter):     if curr_letter == 'a':         print(curr_letter)     else:         print(curr_letter)         prev_letter = chr(ord(curr_letter) - 1)         backwards_alphabet(prev_letter) starting_letter = input() ''' Your solution goes here '''

in c++

2. Consider the following function: def func1(n): output = 1 for i in range (1, n) : output = i return output Rewrite the function as a recursive function.

Write a statement that calls the recursive function backwards_alphabet() with input starting_letter.

Write a recursive function that displays a string reversely on the console using the following header: def reverseDisplay(value):For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.

Below, enter code to complete implementation of a recursive function palindrome() that determines whether an input string is a palindrome or not: 3. palindrome(s):

write a recursive function that checks see if the first letter matches the last letter, return the middle letters and check until only 0 or 1 letters are left. It returns True or False.   Here is python code that needs to be fixed         # Returns the first character of the string str def firstCharacter(str):     return str[:1] # Returns the last character of a string str def lastCharacter(str):     return str[-1:] # Returns the string that results from removing the first #  and last characters from str def middleCharacters(str):     return str[1:-1] def isPalindrome(str):     # base case #1     # base case #2     # recursive case     pass def isPalindrome(string):     reversedString = string[::-1]      if reversedString == string:          return True     else:          return False inputString = input()  string = inputString.replace(" ", "") if isPalindrome(string):     print(inputString,"is a palindrome")  else:      print(inputString,"is not a palindrome")       if __name__ ==…
