My replit code doesn't run?

I am right now on day 17 of 100 days of code and specially this chapter my code doesn’t run. When this happens, I reload the page and start again. It runs after that for few times and then again doesn’t run. Is it something have to do with my computer ???

Using exit() in your program can cause your repl to be stuck on Working… in the next run. This is one possible cause.
