Hello Everyone!

I want to count the sum of digits in odd places and in even places , and after that their difference

we know that first digit it's from the right side

How can I do it with switch?

For example :

A number 23543 :

sum of digits in even places:7 (3+4=7 even places)

sum of digits in odd places:10 ( 2+5+3=10 odd places)

difference: -3 (7-10)

Thank's!!!
