Tried writing the Game of Rotation code again

I wanted to rewrite the gor code using find, but the code didn't work
over several rewrites. Feeling a little unsure about myself, i started
rewriting the Gor code again, from scratch. After several that didnt
work, turns out i kept forgetting to convert n into an integer. Silly
mistakes. Anyway, I am rewriting this code using find.
A spelling mistake & a realisation.

While rewriting GoR code (Hackerrank) I realised that sniffnums also
doesnt understand + & - signs, and it must be fixed to include that too.
