Answer 1

Manoah I don't think so.
Probably CodePlayground throws Execution timed out error based on time , lines and total char count. The expected output is 14 but after appending 1 to the output string the conditions required to throw ETO error are met and 4 is never printed.

@Manoah I'm not totally sure.
Your logic makes some sense too.

Kevin Star You're right, its not displaying exit code 1 like i thought

Answer 3

It's an endless loop.

SL limits your execution time.

So at one arbitrary point, output just stops.

Answer 4

Its showing exit code 1 which means there was a problem with the program so thats why it exited
