I think I overcomplicated the problem by converting it to a string array and then use parseInt to conver it back to int array, that's why this happened...
But I solved it another way already, thank you so much!

I passed all the random test but failed the basic test. It said " For input string: "-" ", can anyone explain to me what does this error means?

Thank you so much!

I'm new to Python, my code was way longer than this, would anyone mind explaining how this work?
