Difference Between Sum Of Even and Odd Digits

Given a number the task is to find the difference between sum of even and odd digits of the number.

Example 1: Let us take a number 3471. Here sum of even digits is 4 and sum of odd digits is 11. Hence their difference is 11-4 = 7.

Example 2: Let us take a number 8316. Here sum of even digits is 14 and sum of odd digits is 4. Hence their difference is 14-4 = 10.

            System.out.println("The difference between the sum of odd and even numbes is "+(oSum-eSum));
        }
