Expected 17, Got 0

Factorial of what number is 17? The question expects something it doesn't explain. Why should the function return 3 values?

Training in Python 3.

I don't know what I am doing wrong but my code times out on Attempt. I tried to see code and input using print to console, couldn't see input for many test cases.

Only thing I was able to figure out was if I remove + chr(255) from the first test case in Sample Tests, I get a timeout because the value at pointer ends up as 1 everytime it gets to [.

If that is an issue, how can that be handled?

Morse Code for SOS is passed as ···−−−··· in one of the test cases while the morse array has SOS as ...---....
If you look closely ···−−−··· is not ...---.... They are different characters.

Shouldn't this test case be fixed?
