Tests have evolved since

Maybe the associated tests were updated in the meanwhile.

I was using C#

I managed to submit my solution.

My confusions comes from the following :

• all assert are in the same function and not in separated methods with name indicating the covered case
• exceptions are not part of the result but just "Unknow error"
• I was not dealing the case where "lst" is empty and thus the execution was generating an "InvalidOperationException"

Thanks for your help, and I hope this explanation will help someone else.

In fact i've already tried submiting at different times and days but I still got the same error message.

I'm always getting "Unknown error" (see https://dl.dropboxusercontent.com/u/16996616/unknowError.PNG ), what should I do ?
