Yeh sure, has to be that. But my question is more about, if this very specific unique unexpected result I get is due to an error in my end, or any preoviosuly reported gaffe in the overal excersise. I will take another look.

it means your code is returning the wrong value(it is returning 79 when the rigght answer is 87)

Hi everyone, good one this one. Queston, if you may:

I got my code to pass all basic test cases, and Attempting results in around 99% complete, but two or three recurrently fail, always with the very same value:
"79 should equal 87"
Any hint? Why is that so specific?

Thanks!
