你需要use extended euclidean algorithm，但不确定正确的做法、最佳实践或需要避免的常见陷阱。
前置条件
- Understanding 的 foundational concepts 在 math
- 熟悉related tools 和数据 formats
步骤
-
1. Set up the environment and inputs
Prepare the input data needed for gcd. Ensure the input meets the expected format and constraints for euclidean. If the operation requires configuration (such as parameters, keys, or mode selection), gather those values now. Validate the input before proceeding to avoid errors in later steps.

2. Perform the gcd operation
Apply the gcd operation to the prepared input. Follow the standard procedure for euclidean: process the input according to the specification, handle any intermediate transformations, and collect the output. If the operation is multi-step, complete each sub-step in order and verify intermediate results.

3. Verify and interpret the results
Check the output against expected properties. For gcd, the result should satisfy specific invariants — verify them. If the output is encoded or transformed, decode it to a human-readable form for inspection. Compare against a known-good reference if available. Document any deviations and their causes.

4. Handle edge cases and optimize
Test gcd with edge-case inputs: empty data, maximum-size data, special characters, and invalid formats. Ensure each edge case is handled gracefully. If performance matters, profile the operation and optimize hot paths. Consider caching, batching, or parallelization where applicable.

预期结果
掌握gcd，能够正确应用、避免常见错误，并在出现问题时进行排查。
常见错误
- Incorrect input format for gcd
- Validate the input against the expected schema before processing. Use a linter or validator to catch format issues early.
- Unexpected output or silent failure
- Add explicit error handling and logging. Test with known inputs and compare outputs against reference values to detect silent failures.
排障指引
- If gcd produces no output, check that the input is non-empty and matches the required format.
- If performance is slow, profile the operation to identify bottlenecks. Consider batching or streaming for large inputs.
