it is not important at all for me
I just wanted to give you my feedback

this cannot be 6kyu
I would say is 8kyu

not a 7 imho

before checking if cols or rows are more than 0, the error I got was not treated in your tests (totalWidht... something)
could've been something more friendly

but cool kata nevertheless

yes, you are correct

very similar if not identical to existing kata

you should've not given the explanation, let people search on internet if they don't know the particularity with if divisible by 100 then also by 400

very good to use linq for an 8kyu difficulty in my opinion

too easy and similar to existing 8kyu katas

too easy

input should've been a string maybe to make it a little bit harder, containing digits and other stuff

great job for creating a kata
it was too easy; what happens if no odd number is found? return -1 or throw an exception?
thanks
