You can console.log the input parameters, so that you can see what is being passed in.

I've got a problem like this, i used rust.

The massage returned by attempt says overflow.

This kata is not an easy 6 kyu. I advice you to practice on easier ones. If you don't manage to do one after some trials, move on, you'll solve it later maybe. You will progress and you will be able to solve harder and harder katas.

how to figure out what the problem is?
I am very new to codewars.
Most of the times, I pass the test but fail the attempt. How can I know what is the problem??
