A special two-digit number is such when the sum of its digits is added to the product of its digits,
the result is equal to the original two-digit number.
Example: Consider the number 59.
Sum of digits = 5 + 9 = 14
Product of digits = 5 × 9 = 45
Sum of the sum of digits and product of digits = 14 + 45 = 59
Write a program to accept a two-digit number. Add the sum of its digits to the product of its digits.
if the value is equal to the number input, then display the message “Special two – digit number”
otherwise, display the message “Not a special two-digit number”.
