Fix this by using signed subtraction. The call to\nmax() will correctly handle any negative numbers that are produced.\n\nApply the same fix to the other timings, even though those subtractions\nare less likely to underflow."}], "lastModified": "2025-06-18T13:47:40.833", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
