Exact delays, ranges, repetition operators, and sequence-composition semantics under realistic waveforms.
1. Exact Delay Then Bounded Hold [Medium]
2. Goto Repetition With Sparse Events [Medium]
3. Nonconsecutive Repetition [=2] [Hard]
4. Sequence and Operator [Medium]
5. Intersect End-Time Mismatch [Hard]
6. within and Alternative Windows [Hard]Work each puzzle before reading the solution: predict the exact output or answer, name the rule that governs it, then check yourself.
