@neverlish 님, 8주차도 고생 많으셨습니다~
코드가 깔끔하고 명확해서 go
를 잘 모르는데도 잘 이해할 수 있었던것 같습니다!
벌써 절반이 넘었는데, 앞으로도 좋은 풀이 많이 공유해주시면 좋겠습니다.
새해 복 많이 받으시고, 남은 휴일도 편안히 보내세요!!

carry 가 발생하는 경우에는 O(log n)
의 복잡도가 필요할 것으로 보여요
ex) 0b1111
+ 0b1

요건 몰랐던 사실인데 덕분에 배워갑니다 😄

maxValue(counter)
에서 추가적인 시간복잡도로 O(k)
가 발생할 것으로 보여요

요건 코드를 다시 훑어보았는데,
문제 제약사항 중 0 <= k <= s.length 가 있어서,
O(k)를 더한다고 해도 O(2n) 보다 커지지 않을거 같아서, O표기법에 따라서 그대로 O(n) 으로 둘까 하는데 어떨까요

이 이하에서는 commonSubsequence[i-1]
미만의 변수는 사실상 더이상 사용되지 않는것 같아요. 이를 덜어내는 방식으로 공간복잡도 최적화가 가능하지 않을까요?

생각해보니 이전, 현재 포인터만 저장하면 되겠네요!

깔끔한 코드라서 이해하기 좋네요!
이 문제에만 복잡도 분석이 빠져있는데, 의도 하셨을수도 있지만 혹시 실수이실까 해서 코멘트 남깁니다!

요거는 제가 빼먹었네요 ㅎㅎ 감사합니다
병합해보겠습니다! |
