Details
Save as snippet.js and run node snippet.js. Uses built-in Node.js and JavaScript APIs. Use BigInt operands together to avoid precision loss.
BigInt cannot be mixed directly with Number arithmetic or serialized by JSON.stringify without a conversion policy.

Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
