It's not a bug. In that case the runner's name is Second Runner.

Removed the performance requirements from PHP as the reference solution was not working anymore in current PHP versions without increasing available memory of the PHP process.

Haskell fork that adds edge cases that share maximum/minimum values.

Fixed

Resolved and merged. Thanks!

To be fair, "big" and "straightforward" are extremely subjective terms. However, out of consideration for the 8kyu level, I've forked my translation here to limit the random inputs to the same range as the other translations (except PHP).

(edit) I've also updated the description to add the input range for random tests (in all languages but PHP).

The reference solution is broken. ( The large fixed tests are as well. ) This has been raised as the spoiler issue.

I believe the reference solution is currently broken. It does not apply the modulus correctly, so it often produces wrong answers for large inputs.

same. Even following along with the "video" the author describes, my solution passes around 30 per run.

I'm in the same boat. I'm pretty sure I have the right formula but only pass around 30 large tests.

This was a situation that I was also aware of, it was fixed. Thanks ^_~
