charArray가 반복문을 위해서만 사용된 것 같아서
charArray를 생성하지 않고 chatAt을 이용하면 공간복잡도를 O(1)으로 푸는 것도 가능할 것 같은데 어떻게 생각하실까요?
추가적으로 n 이 무엇을 의미하는 걸까요?

n 은 문자열의 길이를 나타냅니다.
말씀하신 데로 charAt을 쓰면 sToChar와 tToChar 를 사용하지 않아도 되어서 공간복잡도가 O(1)로 끝날 수 있어서 좋은 선택지인 것 같습니다! 👍

nit: 접근 제한자를 일관적으로 붙이거나 생략해주면 불필요한 오해의 소지를 없앨 수 있을 것 같아요.

@f-exuan21 님, 본 PR 계속 Draft 상태로 두시고 병합하지 않으시는 이유가 있으신가요? |
