| You are solving a competitive programming problem. | |
| Problem directory: /app | |
| - Read statement.txt for the full problem description | |
| - Time limit: 2.0s, Memory limit: 1024m | |
| - 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. | |
