Compute legal bin counts and percentages from sampled traffic, then explain why apparently hit values may not contribute to coverage.
1. Auto vs explicit bins with illegal transition context [Medium]
2. Default bin denominator puzzle [Easy]
3. Bin array math with mixed declarations [Hard]
4. Transition bin sequence counting [Medium]
5. illegal_bins vs ignore_bins accounting [Medium]
6. Same traffic, different denominator [Hard]Work each puzzle before reading the solution: predict the exact output or answer, name the rule that governs it, then check yourself.
