영상 마지막 로직에 대해 질문드리려고 문의드립니다.onMount와 onDestory 함수로 setInterval과 clearInterval을 생명주기에 맞게 실행시키게되어 setInerval과 clearInterval을 한번씩만 실행시키는 거 같은데 $(리액티브선언문) 으로 setInterval과 clearInterval 를 작성 시setInterval과 clearInterval이 반복적으로 호출되어 생성되었다 지웠다 하는것 같아 보이는데이 방식이 메모리 영역에서 괜찮은건지 궁금합니다!<script> let intervalEventText; let eventIndex = 0; const eventText = [ "영화 정보 업데이트", "신규 영화 추가", "이벤트 진행중" ] import { onMount, onDestroy } from 'svelte' /** 리액티브 선언문 방식 */ $: { // 이벤트 인터벌 제거 clearInterval(intervalEventText); console.log(eventIndex) // 일정 시간 경과 후 eventIndex를 1 증가 intervalEventText = setInterval(() => { eventIndex += 1; if (eventIndex >= eventText.length) { eventIndex = 0; } }, 1000); } /** onMount & onDestory 방식 */ // onMount(()=>{ // intervalEventText = setInterval(() => { // eventIndex += 1; // if (eventIndex >= eventText.length) { // eventIndex = 0; // } // }, 1000); // }); // onDestroy(()=>{ // console.log(eventIndex) // clearInterval(intervalEventText); // }) </script> <p>{eventText[eventIndex]}</p>

UI 강의 22:16에서 실행을 했을 아래와 같이 오류가 발생 하네요..{ Button* ui = new Button(); ui->SetSprite(GET_SINGLE(ResourceManager)->GetSprite(L"Start_Off"), BS_Default); ui->SetPos({ 200, 200 }); uis.pushback(ui); }ui->SetSprite 부분을 //처리할 경우 오류가 안나는 걸로 봐서는 여기서 뭔가 잘못된 것 같은데 아무리 찾아도 안나오네요..

13:04 질문이 있습니다.방구를 뀌었을 시 상하좌우로 퍼져나간다고 문제가 전제되었을 때1. 크레이지 아케이드의 물폭탄처럼 해당 지점의 상하좌우로 퍼져나가는지2. 그게 아니라면 오염받은 지점 역시 다음번에 그 지점으로 부터 오염이 이어나가져 주는지는 어떻게 구분하시나요?조금 더 직관적으로 질문을 드리자면 Connected Component로 할 경우 각 4개로 구분이 되므로1번 상황의 경우 1번째 육지에서 2행1열에 서 뀌면 한번에 오염이 되겠지만2번 상황의 경우엔 아무데나 뀌어도 전체가 오염이 될 것입니다.혹시 이런 판단을 어떻게 내리시는지 여쭤봐도 될까요?코딩테스트에서 문제에 대해서 직관적으로 이해가 항상 제일 어려운 문제인 것 같습니다. ㅜㅜ 너무 문맥 파악이 어렵네요.ps. 추가된 질문인데 한번 방귀를 뀔 때 4방향만 오염된다고 했을 때 혹시 만약 저 상황에서 최소한의 방귀로 오염시킬 수 있는 횟수를 구하라고 한다면 추가적으로 어떤 로직이 필요할까요?

안녕하세요!Header.jsx 파일에서 이 오류가 사라지지 않아서 질문 드립니다! 어떻게 해결해야 하나요...?

저의 경우 client sql 버전이 안맞다고 나옵니다 workbench는 8.0Mysql 9.0 Configurator로 설치했습니다  stackoveflow에서 찾아보니ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';Where root as your user localhost as your URL and password as your passwordThen run this query to refresh privileges:flush privileges;Try connecting using node after you do so.If that doesn't work, try it without @'localhost' part. 이런 답변이 있는데 어떻게 적용하는지 알 수 있을까요? 

리포지토리 계층에서 모든 데이터 액세스 기술에서 발생하는 예외는 DataAccessException으로 랩핑되어서 던져진다고 말씀하셨는데 받는 쪽인 서비스 계층에서는 DataAccessException의 서브클래스 타입의 예외를 받게 될거 같은데요. 서비스 계층에서 받게 되는 예외가 예를 들어 DuplicateKeyException이라서 처리를 하게 된다면 서비스 계층은 특정 리포지토리의 예외에 종속적이게 될거 같습니다. 그래서 컨트롤러 단으로 예외를 넘겨 ExceptionHandler로 처리해주는 것이 좋은 방법일까?에 대해서 질문 드리고 싶습니다.근데 만약 서비스 계층에서 처리한다면,// @Service 안에 있는 있는 일부 코드 (회원가입 로직) public boolean saveCustJoinInfo(UserDto userDto) { String pwd1 = userDto.getPwd().split(",")[0]; String password = passwordEncoder.encode(pwd1); userDto.setPwd(password); try { userDao.insertUser(userDto); return true; } catch (DataAccessException e) { return false; } }이렇게 처리해도 문제가 없는가에 대해 궁금합니다. 예외 처리에 대한 여러 블로그들을 읽어봤는데 다수의 사람들이 사용자 정의 예외클래스를 정의해서 던지도록 한 이유도 궁금합니다.만약 이 방법이 좋지 않다면 어떤 계층에서 처리하면 특정 계층이 기술에 종속적이지 않게 예외를 처리할 수 있는지 조언해 주시면 감사하겠습니다. 토비님의 스프링 강의를 일주일 만에 완강했는데 너무 좋은 강의라 부트 강의도 구매하였습니다ㅎㅎ 아키텍처에 대한 강의도 고려하시고 있다고 하셨는데 기다리고 있겠습니다!!

이 강의에서 나온 3가지 버전에서 동작을 보면 구조체를 초기화한 내용을 텍스트 파일 안에 저장하고, 텍스트 파일의 내용을 변경하여 다시 읽어들인 다음에 콘솔창에 출력하는 것으로 이해했습니다. 이중포인터를 사용하는 부분은 잘 이해하진 못했지만 구조체 포인터로 하는 부분은 구현도 했구요. 근데 바이너리 파일의 경우에는 단순히 읽거나 쓰는 용도로 사용하는 것이지 별도의 파일 편집기로 내용을 수정하기가 거의 불가능하다고 생각하고 있었는데 제 생각이 틀린걸까요? 그냥 교수님이 쓰신 코드를 따라 쳐봤지만 이게 무슨 의미를 가지는 것인지 잘 이해가 안갑니다... 바이너리 파일 입출력을 사용하는 경우 read_books 함수의 사용처가 뭔가요?
