Quick Summary
- Simulate a bottom-up tokenization process where multi-character tokens are built by merging previously defined adjacent tokens.
- Process tokens in strict index order, applying left-to-right merges exactly once per pass without re-scanning newly formed tokens.
- Efficiently manage dynamic sequence updates and validate merge rules against the evolving token stream.
What This Tests
- Simulation and state management over mutable sequences
- Efficient data structure selection for frequent element removals
- Event scheduling with strict ordering constraints
- String-to-ID mapping and fast lookup structures
- Validation of structural invariants during iterative passes
