The tie-breaking is working correctly - for avalanche, card-a comes first alphabetically when balances and APRs are equal; for snowball, it's the same since both have equal balances and APRs.\n\nHere's a summary of what I've accomplished:\n\n1. Created a Python script (`solve.py`) that implements both debt avalanche and snowball payoff methods\n2. Used `Decimal` for precise financial calculations with proper rounding\n3. Implemented correct ordering rules for both methods:\n   - Avalanche: highest APR first, ties broken by smaller balance, then name\n   - Snowball: smallest balance first, ties broken by higher APR, then name\n4. Followed the exact monthly simulation process specified in the requirements\n5. Handled edge cases properly:\n   - Budget below minimum payments\n   - Debts not paid off within 600 months\n6. Generated output in the exact required format with proper JSON structure\n7. Verified the implementation works correctly with multiple test cases\n\nThe script reads from the input file specified in the command line, processes the debt payoff simulation for both methods, and writes the results to the output file, all while maintaining precision to the cent as required.",

The tie-breaking is working correctly - for avalanche, card-a comes first alphabetically when balances and APRs are equal; for snowball, it's the same since both have equal balances and APRs.\n\nHere's a summary of what I've accomplished:\n\n1. Created a Python script (`solve.py`) that implements both debt avalanche and snowball payoff methods\n2. Used `Decimal` for precise financial calculations with proper rounding\n3. Implemented correct ordering rules for both methods:\n   - Avalanche: highest APR first, ties broken by smaller balance, then name\n   - Snowball: smallest balance first, ties broken by higher APR, then name\n4. Followed the exact monthly simulation process specified in the requirements\n5. Handled edge cases properly:\n   - Budget below minimum payments\n   - Debts not paid off within 600 months\n6. Generated output in the exact required format with proper JSON structure\n7. Verified the implementation works correctly with multiple test cases\n\nThe script reads from the input file specified in the command line, processes the debt payoff simulation for both methods, and writes the results to the output file, all while maintaining precision to the cent as required.",
