## Problems

## Scoring

Pass/Fail — Ranked

**Explanation:**

Each problem is pass/fail. Participants are ranked by the number of solved problems, breaking ties by penalty (sum of time + 20 minutes per wrong submission, for all solved problems). Time is rounded to minutes.

## Standings

- Standings are shown without limitation.
