Quick Summary
- Find a hidden 4-digit code using an interactive function that reports exact positional matches.
- Optimize for minimum queries by first identifying digit frequencies, then determining their correct order.
- Leverage systematic testing to deduce the solution efficiently without brute-forcing all combinations.
What This Tests
- Algorithmic optimization and query minimization
- Deductive reasoning and information gathering
- State tracking and constructive problem solving
