따라치기에 바쁘고 코드를 적으시는데 이해못하면 잘못 듣고있는건가요? 자바 강의는 다 들었는데 뭘하시는지를 모르겠고 따라적기만 하고있습니다..

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.http://boj.kr/d5dbeef9edfd46d4b6ca8eda86668fcd문제는 해결했는데 궁금한 점이 생겨 질문 드립니다.23번째 줄에서 배열 초기화 할 때 fill함수가 아닌 memset함수를 사용해야 하는 이유가 궁금합니다.fill함수를 쓰면 출력 결과가 안 나오는데 어떤 문제 때문에 그런건지 궁금합니다. 코드에 문제가 있는 건가요? -> fill(&visited[0], &visited[0]+10001*10001, 0);  

빌드하고 테스트? 하는 작업 할때 명령어 오류가 발생합니다.install 할때도 serve 가 잘 안되는거 같습니다. 실행하는 디렉토리 위치나 필요한 파일이 있을가요 ..? 

안녕하세요! 로그아웃 후 계속 auth/me후 계속 req에서 쿠키가 존재해서 문의 남깁니다! application탭에서 쿠키는 잘 삭제가 되고 네트워크 탭에서도 logout이 성공적으로 이루어지는데 reload하면 바로 auth/me가 계속 200코드와 함께 user가 전달됩니다. 콘솔에도 찍어봤는데 계속 req에 쿠키가 같이 전달되고 있어서 요. 서버도 껐다 켜보고 했는데도 계속 그래서 문의드립니다!client/src/context/auth.tsxclient/src/components/NavBar.tsxserver/src/middlewares/auth.tsserver/src/routes/auth.ts

우선 제가 작성한 코드링크는 다음과 같습니다. (주석 포함)http://boj.kr/5cf259ef97444ada8ad4e9391096d3b90번 노드가 root 가 아닌경우루트 노드가 삭제되는 경우 => result = 0루트 노드가 단독으로 남는 경우 => result = 1까지 고려해서 케이스 분류를 잘게 하여 작성을 했는데...결과가 틀렸다고 나와서 어느 부분을 놓쳤는지 통 모르겠습니다 ㅠㅠ 

위 사진처럼 프로그램을 진행시켰을때 위에부분이 잘려서 나옵니다.제가 코드를 잘못 친 것은 아닐까 하는 마음에 다른 코드들도 여러번 쳐봤으나 저런 경우가 꽤나 있습니다.무엇이 문제일까요??

안녕하세요, 강사님 강의 잘 수강하고 있습니다!3-2 매장 데이터 불러오기 강의에서매장 정보가 담긴 json 파일은어디서 구해오는 파일인지 궁금합니다.올려주신 json파일로 강의 수강 진행하고 있지만, 원하는 다른 매장 데이터로 이용하고 싶을 경우 어디에서 이 json 파일을 얻어와야 하는 것인가요? 감사합니다!

 ctrl +c / ctrl+ r 으로 문자 치환하는 부분 입력이 안됩니다. ctrl + r 눌러도 아무것도 실행이 안되는데 뭐가 문제일까요..

설정이 파란색이면 설정이 잘 바뀌는데 주황색이 되면 바뀌지 않는 것 같습니다.혹시 어떻게 하면 바꿀 수 있는지 알 수 있을까요??

강의에서는 const ar = []ar.length === 0 ?console.log("true"):console.log("FALSE");이런식으로 코드를 보여주셨는데제가 궁금한건 const ar = []; !ar.length ? console.log("Something exist"):console.log("EMPTY");이렇게 코드를 작성하면 물론 Something exist가 출력이 되겠지만제가 궁금한건 저기서 ar.length === 0 // 또는 FALSY? 인지ar.length ==0 // 또는 FALSY ?인지 궁금함다.질문을 한줄 요약하면삼항 연산자에서 조건 비교를 할때 내부적으로 == 가 사용되는지 아니면 === 로 사용되는지 궁금함다. 

뭐가 문제인지 모르겠습니다 스승님!kubectl delete -f metallb.yaml 후 다시 apply 해봐도 pending 상태에서 안바뀌네용...

분명 결과가 에러가 떠야 맞는데... 이상해요 그리고 강사님 화면처럼 결과가 뜨지도 않구요저는 윈도우 쓰고 있는데 이건 운영체제가 달라서 그런건 아닌거같은데... 뭐가 문제일까요?ㅠ

안녕하세요! 프로세스 동기화에서 세마포어, 뮤텍스, 모니터 개념을 찾아보면 "프로세스 간에..", "스레드 간에..", "프로세스 또는 스레드 간에.." 글마다 설명이 다르던데 기준이 프로세스가 될 수도 있고, 스레드가 될 수도 있는건가요? 프로세스와 스레드 용어가 섞이다보니 헷갈려서 질문 드립니다!

안녕하세요 큰돌님늘 강의에 신경써주셔서 감사합니다. 2-H, 2659번 비밀번호 발음하기, 코딩하다가 틀렸다고 나와서.. 질문드리려고 합니다. 문제에 대한 강의도 확인했구요. 로직도 이해한 상태입니다.그런데 제 코드를 봤을 땐, 어디서 오류가 났는지.. 반례를 도저히 못 찾겠어서 글을 써 봅니다. 혹시 제 코드에서 로직 오류가 있는지 피드백 주실 수 있으실까요?코드 길이나, 반례 등 어떠한 피드백 전부 환영입니다. 제 코드는 링크로 첨부하겠습니다.감사합니다. http://boj.kr/b1f8019ccf3d4f03ac0de822cb532282

안녕하세요강의 수강 중 프로젝트 폴더를 다른 폴더에 저장하고 싶어서 이동시켰습니다. 그 후 인텔리제이로 프로젝트를 열어보니 폴더가 보이지 않는 오류가 있어 구글링해서 오류를 해결하고자 했는데요. (참고했던 블로그: https://solbel.tistory.com/2712)그 후 다시 확인해 보니 디렉토리 구조도 정상적으로 다 뜨지 않는 것 같고 스프링 프레임워크도 사라진 것 같습니다...ㅠ일반 자바 프로젝트는 폴더 위치를 옮겨도 문제가 생기지 않았는데 스프링 프로젝트만 이런것인지.. 혹시 해결할 수 있는 방법이 있을까요?
