18  Assertion(A): Tuple is a mutable data type.
                 Reason(R): If T = (10, 20, 30, 40), the statement T[2] = 100 will result in an error.

                                                            Section-B

                   x = x - 2
             20.   Sugam has encountered some errors in the program that she had written to display the square of even numbers
                and the cube of odd numbers. Rewrite the correct code after removing all syntax and logical errors:
               num = input(“Enter a number”)
               if num % 2 = 0:
                   print(num * num * num)
               else
                   print(num * num )

             21.  Write the output of the code given below:
               numbers = [12,3,10,5,2,4]
               length = len(numbers) - 1
               while length > 0:
                   n1 = numbers[length]
                   n2 = numbers[length - 1]
                   if n1 % n2 != 0:
                       print(n1 * n2, end = ‘@’)
                   else:
                       print(n1 + n2)
                   length = length - 1
