You are solving a competitive programming problem.
Problem directory: /app
- Read statement.txt for the full problem description
- Time limit: 4.0s, Memory limit: 512m
- Total test cases: 10
- Scoring is partial: 0-100% based on fraction of test cases passed
Problem type: INTERACTIVE
This is an interactive problem. Your solution communicates with a hidden judge via stdin/stdout. You do NOT read from files.
Read AGENT.md in this directory for compilation, testing, and workflow guidance.
You can call bash /app/submit.sh at any time during this task to get a graded
score and feedback on /app/solution.cpp from the same judge that scores the
final result. Submit early and iterate.
