10. Multiply Evens by Odds
Create a program that multiplies the sum of all even digits of a number by the sum of all odd digits of the same number:
• Create a method called GetMultipleOfEvenAndOdds()
• Create a method GetSumOfEvenDigits()
• Create GetSumOfOddDigits()
• You may need to use Math.Abs() for negative numbers
