한 주 동안 5문제를 모두 푸시다니, 정말 수고 많으셨습니다.
4주차도 파이팅입니다.🔥

저도 문자열을 정제 후, 반복문을 통해서 문제를 해결했습니다.
한번 푸신 후 좀 더 최적화된 풀이까지 작성하신 부분 멋집니다 👍

string으로 처음에 풀이하신 후,
10진수를 2진수로 변환하는 방식으로 최적화 하신 점 좋습니다.
이 문제를 비트를 조작해서 풀어보시는 것도 추천드립니다!
풀이 방식이 다양하고, 재미있습니다.
시간복잡도나 공간복잡도 면에서는 비트로 풀어도 동일합니다.
다만, 실행 측면에서는 나눗셈보다 비트가 더 유리합니다.
시간이 부족하시면, 달레님 블로그 풀이를 참고하셔도 좋을 듯 합니다. 😄

백트래킹 쉽지 않네요. 저도..AI 도움을 많이 받았습니다. 🥲
