This commit message captures the essence of the change: fixing the implementation of the apply() method in the PatternRule class to correctly handle sequence operations and indexing.
The key changes are:
1. Use `sequence[position]` instead of `sequence[position - 1]`
2. Adjust PREV_PLUS condition to use `position > 0`
3. Use `sequence[position - 1]` for previous element reference
Would you like me to elaborate on the specific changes or rationale?
This commit introduces a new `ArithmeticDataset` class that:
- Combines complex and simple arithmetic task generation approaches
- Provides configurable task generation via `ArithmeticDatasetConfig`
- Supports deterministic task generation
- Implements dataset interface for easy use with HuggingFace datasets
- Adds comprehensive test coverage for the new implementation
Changes include:
- Refactored `basic_arithmetic.py` to use a unified dataset approach
- Added configuration validation and flexible generation options
- Created test suite to validate dataset behavior
- Removed file generation methods in favor of in-memory generation
