String Palindrome

Aim: Implement a program to check if a string is palindrome or not

Algorithm:

1.      Input a String

2.      Make it suitable for caseless comparison using casefold() function

3.      Reverse the string

4.      Check if the string is equal to its reverse then go to 5 else go to 6

5.      Print string Is a Palindrome go to step 7

6.      Print string Is Not a Palindrome

7.      Stop

Program:

# Program to check if a string  is palindrome or not

# take input from the user

my_str = input("Enter a string: ")

# make it suitable for caseless comparison

my_str = my_str.casefold()

# reverse the string

rev_str = reversed(my_str)

# check if the string is equal to its reverse

if list(my_str) == list(rev_str):

   print("It is palindrome")

else:

   print("It is not palindrome")

Output :

Enter a string: malayalam

It is palindrome
