고생 많으셨습니다! 👍
- 작은 함수 단위 분리
- if else문 줄이기 + 중간 탈출
- 네이밍
부분 신경 써주시면, 가독성이 더 좋아질 거 같아요!

검증과정을 따로 함수로 빼서, 모아서 보면 더 좋을 것 같아요!

answer에 값을 넣어서 마지막에 리턴하는 것보다,
중간에 탈출할 수 있게하면 더 좋을 것 같습니다!
그리고 마지막 else는 제거할 수 있을 거 같아요

Comp가 무엇을 뜻하는지 잘 모르겠어서, 풀어서 쓰는 것도 좋을 것 같아요
LR보다 더 이해하기 좋은 네이밍이 있을 것 같아요! 저는 page라고 했어요

개인적으로 i를 바꾸는 것은 위험하다고 생각합니다!
i를 바꿔야한다면, for문 대신 while문이 더 괜찮을 거 같아요

index로 조회하는 것 보다 더 가독성 좋은 방법이 있습니다!
Suggested change
| for(int i = 0; i < visitors.size(); i++) { | |
| for(String visitor: visitors) { |
