Python program to check if a string is palindrome or not

Python program to check if a string is palindrome or not

Answer:

my_str = 'Madam'
my_str = my_str.casefold()

rev_str = reversed(my_str)

if list(my_str) == list(rev_str):
   print("The string is a palindrome.")
else:
   print("The string is not a palindrome.")


Output:

The string is a palindrome.

{     
   int temp;
   temp = a;
   a = b;
   b = temp;
}

void display(int *array, int size)

   for(int i = 0; i      cout << array[i] << " ";
   cout << endl;
}

void selectionSort(int *array, int size)
{
