Let us say we have two numbers num1 = 19 and num2 = 65. The product of num1 and num 2 is 1235.
The odd numbers are 1,3 and 5 and their sum is 9. The below program will do so
from System import *
from System.Linq import *
from System.Numerics import *
class Program(object):
def Main(args):
num1 = 19
num2 = 65
#Approach 1
Console.WriteLine("The sum of odd digits of the product of {0} and {1} is {2}", num1, num2, (num1 * num2).ToString().ToCharArray().Where().Select().Sum())
#Approach 2
Console.WriteLine("The sum of odd digits of the product of {0} and {1} is {2}", num1, num2, Array.ConvertAll((num1 * num2).ToString().ToCharArray().Where().ToArray(), ).Sum())
Console.ReadKey()
Main = staticmethod(Main)
Output
------ The sum of odd digits of the product of 19 and 65 is 9
