if (Head == null )     Head = newRoom; if (Tail != null) { } 이부분에서 if (Tail != null) 을  if (Head != null )이라고 써도 되나요?  Head가 존재하면 Tail은 무조건 존재하니까 그냥 else문 써도 될거 같은데  Tail != null 이라고 쓰신 이유가 궁금해요

//2D 배열에서 indexOf() 메소드로 포함 여부를 판단할 수 없기 때문에 별개의 function을 만들었습니다! function isItIncluded(array1, array2) { for (let i = 0; i < array1.length; i++) { if (array1[i][0] == array2[0] && array1[i][1] == array2[1]) { return true; } } return false; } function solution(tests) { let tempArr = []; let trueAnswer = []; for (test of tests) { let numStud = test.length; // = 4 for (let i = 0; i < numStud - 1; i++) { for (let j = i + 1; j < numStud; j++) { tempArr.push([test[i], test[j]]) } } } for (let i = 0; i < tempArr.length; i++) { let reversed = [...tempArr[i]].reverse(); if (isItIncluded(tempArr, reversed) == false) { if (isItIncluded(trueAnswer, tempArr[i]) == false) { trueAnswer.push(tempArr[i]); } } } //console.log(trueAnswer); return trueAnswer.length; }

질문1 모바일 웹 앱을 만들었는데요 slick slider 부분에 slick-arrow display:none;하고, 컨텐츠 내에서 padding magin 처리도 잘 해주었는데 가로 스크롤이 안 없어져요 그래서 overflow-x : hidden; 이라는 속성값이 있어서 처리 해쥤는데 괜챤을까요? 아님 원인을 제대로 찾아야 할까요?   질문2 Header 부분에서 로그인과 회원가입을 UIkit Modal로 했는데 Modal 이뜰 때 오른 쪽으로 살짝 밀렸다가 X 버튼 눌럿을 때 다시 제자리를 찾는 덜컹거림 해결은 어떻게 하나요? ( 참고로 모바일에서는 보이기가 그래서 이부분을 빼기는 했는데, pc상에서 그래서 요)   이 두가지 말고는 모두 잘되요  

안녕하세요 제로초님  엑시오스 인터셉트에서 accessToken이 만료되서 가지고 있던 refreshToken으로 다시 accessToken을 갱신해서  특정 데이터를 다시 요청을 하는데.. 만약 refreshToken 마저 만료되면 에러가 발생할테니 그 부분에서도 에러처리를 해줘야 하는거겠죠? 사소한 질문이지만 .. 답변해주시면 감사하겠습니다.

안녕하세요 영한님 소중한 강의 잘 듣고 있습니다.   ppt 85쪽에 AutoAppConfig.java 파일에서  @Configuration @ComponentScan( excludeFilters = @Filter(type = FilterType.ANNOTATION, classes = Configuration.class)) public class AutoAppConfig { } 이 소스 코드에서 앞서 만든 예제 코드인 AppConfig, TestConfig의 설정정보는 현재 AutoAppCofig를 컴포넌트 스캔을 사용한 설정 정보와 중복 등록하지 않기 위해서  excludeFilters 써서 제외했다는 건 이해가 가지만 필터가 Configuraion.class인 클래스들은 다 제외한다는 거라면 현재 AutoAppConfig.java파일에 @Configuration도 제외되는게 아닌가요? 이 부분이 조금 의아해서 질문 올립니다.  감사합니다.
