Algorithm Playground
Compare a promised Deutsch-Jozsa instance with a four-item Grover instance through amplitude tables.
Investigation
Trace one oracle sign pattern, one final Hadamard pattern, and one Grover diffusion reflection.
Learning evidence
Two amplitude tables and a caveat distinguishing query advantage from product readiness.
Interactive check
Guided local calculation. Simulated results, not quantum hardware or a full circuit simulator.

Explanation
In the ideal four-item example, one Grover iteration makes the marked 11 outcome certain.

Completion checks
- States the promise.
- Tracks signs before probabilities.
- Avoids claiming universal or immediate practical speedup.
