Run the following code in the custom invocation tab with pypy3.6

import random

print('Hello world!')

This gives the following verdict:

Runtime error: exit code is 13131313

Any ideas why? This also happens with pypy2.7, but not when using the CPython interpreters.

The 2019 North American Qualifier (NAQ) will be held tomorrow. The NAQ is an online, pre-regional programming contest to help coaches choose teams for regional competitions (or serve as practice). The contest begins at 2019-10-05 18:00 UTC. Official participants who have already registered can access the problems at https://naq19.kattis.com/.

There is also a slightly delayed open mirror where anyone can compete. The open mirror begins fifteen minutes after the official contest, and is available here: https://open.kattis.com/contests/naq19open.

More details here: http://cs.baylor.edu/~hamerly/icpc/qualifier_2019/. Past versions: 2018, 2017.

Good luck to all competing!
