Funny thing is i did it EXACTLY this way :P.
Except i used Convert.ToChar();
Nice man

Explain what?

Can someone explain?

"You solution should" => "Your solution should"

Thanks, didn't know console.log worked here.

That helped to find the problem.

Maybe your code got caught in an infinite loop?

You can always debug easily by using console.log or equivalent.

I'm getting "STDERR: Process was terminated. It took longer than 12000ms to complete".
My code only has 4 lines with only one in a loop, how can that takes more than 12 seconds?

Hint: Description says "a length of at least 3, but could be very large".

I think it's possible for valid solutions to be invalid if this happens:

1. The test cases are updated and some solutions become invalid (possibly by mistake?)
2. The test cases are updated to fix the mistake, but the solutions are already invalid and cannot be changed back

"these solutions now no longer pass"
Just tried and the solution did pass (since it's almost the same as the valid ones).

Some basic math:
(x - z * y)/ z = x/z - (y * z)/z = x / z - y
