5. A Palindrome is a string that reads the same in both directions e.g. "a level is level a". a) Write Python code that defines an iterative function to check whether a string is a Palindrome. [6 marks] b) Write Python code that defines a recursive function to checks whether a string is a Palindrome. 6 marks] c) Suppose you will use doctest module to test your program. Write the docstring which contains at least five test cases. [6 marks Describe an advantage of one of the functions over the other d) 12 marksl

Answer 1

5b)

1 def pal(s): return str(s) str(s[::-1]) 3 s-input("Enter the string ") 2 4 5 if pal(s)-True: 6 print("The entered string is a palindrome") 7- if pal(s) -False: 8 print("The entered string is not a palindrome")

Output

Enter the string: 1233211 The entered string is not a palindrome

code for copying

def pal(s):
return str(s)==str(s[::-1])
s=input("Enter the string : ")

if pal(s)==True:
print("The entered string is a palindrome")
if pal(s)==False:
print("The entered string is not a palindrome")
