💡 What:
label_section함수 내에서 마지막 라벨의 등장 위치를 찾기 위해 사용되던 전방 탐색str.find()루프를 후방 탐색str.rfind()로 변경했습니다.🎯 Why: 기존 구현은 대상 문자열 전체를 앞부분부터 순차적으로 탐색하여 각 라벨 위치를 리스트에 담는 불필요한 O(N) 오버헤드를 유발하고 있었습니다.
rfind()를 사용하면 뒤에서부터 탐색하여 마지막 인덱스를 직접 찾을 수 있어 성능 오버헤드가 개선됩니다.📊 Impact: 라벨 등장 위치 탐색과 관련된 O(N) 오버헤드가 제거되어, 긴 로그를 스캔할 때 성능 저하를 방지할 수 있습니다.
🔬 Measurement: 전체 단위 테스트 스위트를 실행하여, 이 최적화 작업이 기존 동작을 깨뜨리지 않고 성공적으로 수행됨을 확인했습니다. (커버리지 100% 유지)
