 ## 2026-09-01 - 대용량 문자열 서브스트링 스캐닝 루프 최적화
 **Learning:** 긴 텍스트에서 여러 기준 문자열(`candidate`)을 탐색하여 다음 구역의 시작점을 찾을 때, 텍스트 전체에 대해 반복적으로 `text.find(candidate)`를 호출하면 O(N)의 비효율적인 중복 스캐닝 오버헤드가 발생합니다. 특히 가장 가까운 시작점을 찾기 위해 모든 후보를 스캔할 때 이 문제가 심화됩니다.
 **Action:** 기준점(`start`)을 잡은 후, `idx = text.find(candidate, start, end)`를 사용하여 검색 범위를 동적으로 축소(`end = min(end, idx)`)하십시오. 이렇게 하면 불필요한 스캐닝 오버헤드를 막고 검색 범위를 안전하게 줄여 매우 큰 성능 향상을 얻을 수 있습니다.
+## 2024-11-23 - Python 파싱 로직에서 개별 문자 루프 추가(O(N^2)) 회피
+**Learning:** Python 문자열 파싱 시, 선형 루프 안에서 문자 하나씩 `output.append(text[i])`를 호출하면 함수 호출 오버헤드와 함께 큰 병목이 발생할 수 있습니다. 특히 입력 텍스트가 매우 길어지면 메모리 할당 및 리스트 확장 비용이 O(N^2)에 가까운 영향을 줄 수 있습니다.
+**Action:** 긴 문자열을 파싱할 때 `while` 루프 등에서 매치되지 않은 텍스트를 처리하려면, 인덱스를 이용해 탐색(scan ahead)한 뒤 스트링 슬라이싱(`output.append(text[start:cursor])`)을 통해 일괄적으로 매치되지 않은 부분 전체를 잘라내어 리스트에 추가하십시오.
