I think if you can go without Linq, you may only utilize the standard methods and logic.

hi there, this is like my solution. Im trying to learn Linq as well, but i feel like an old school programmer. I dont use Linq for this kind of tasks. My question is, is this better than using Methods from Linq?
(like the first solution we have here, with Sum()). i find in every kata task this problem, easy ones that are solved with a method from Linq.
