Not StackOverflowException, just OverflowException ;)

Tests have evolved since

how did you passsed test?

This solution does not work anymore as there is an overflow. BigInteger should probably be used.

Maybe the associated tests were updated in the meanwhile.

How this code pass the test??? my first attemp with something similar failed 3 of the test... maybe the test where updated since this???

That was my fist try it did not pass BigInts and Null value :(

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 ?
