dangerouslySetIntterHTML 작성시__html 프로퍼티에 빨간줄이 생기는데강의대로 작업해도 군데군데 빨간줄이 생기는데타입체크가 더 필요한건가요

안녕하세요 항상 좋은 강의 감사합니다.전 강의 args와 현재 강의를 듣고 제가 이해를 잘 하지 못한 것 같아 질문 하나 드립니다.해당 강의에서 "args, @args, @target은 실제 객체 인스턴스가 생성 되고 실행될 때 어드바이스 적용 여부를 확인할 수 있다." 고 하셨습니다.1.전 강의 args에서는 spring을 통한 테스트가 아니었기 때문에 모든 스프링 빈에 AOP를 적용 하려는 것을 생각하지 않아도 되는게 맞을까요?2.args를 테스트 할때는 왜 스프링으로 빈 등록을 할 필요가 없었을까요?String, Object는 java.lang은 이미 가지고 있고, args(), args(..), args(*)등은 인스턴스 정보가 필요 없고 만약 Custom한 객체 args(Parent)같은 타입이 들어간다면 자동으로 스프링 동작이 필요한 걸까요?기초적인 질문이라 죄송합니다.

for i, v in OrderedDict(sorted(word_count.items(), key=lambda t:t[1], reverse=True)).items(): print(i,v) 해당 코드에서 정확히 t:t[1]가 어떤 의미인지 조금더 자세하게 설명해주실수 있을까요? 여태 듣던 강의에서 나왔었는지가 확실하지 않아 여쭤봅니다. 감사합니다.

Union 에서 Enum 으로 바로 넘어가는데Tuple 에 대한 설명이 없는 이유가 있을까요?

Camera Controller에서 카메라를 찾으려고 해도 None 표시만 뜨고 Main Camera는 안나와서 할당이 안되고 오류가 뜨네요 ㅜㅜ

윈도우의 커맨드와 맥 터미널의 단축기가 달라 입출력 방향 재지정을 따라할 수 가 없네요ㅜㅜ혹시 괜찮다면 맥 터미널에서 강의에서와 같이 하려면 어떻게 해야할지 알 수 있을까요???

안녕하세요 선생님,clear() 함수에서 this.head = null 이랑 this.count = 0으로 하는게 왜 리스트에 있는 기존 정보를 지우게 되는지 이해가 안되는데 추가 설명해주실 수 있을까요?

강의 5:00~ 보시면 맵에 키값에 fixDiscountPolicy가 들어가는데 어떻게 할당되는건지 이해가 되지 않습니다. ㅠㅠ

함수 선언 부분에서void PrintStatInfo(const char* name, const StatInfo& info);부분에서 빌드를 하면 "확인 할 수 없는 외부참조 입니다"라는 오류가 뜨면서 되지 않습니다.혹시나 해서 const를 지우고 StatInfo& info만 했을때는 정상적으로 실행이 돼서 const 부분이 문제인거 같은데 어떤 이유로 이런건가요??

강사님 화면에서는 안보여서 깔끔해 보이네요.아 그리고 지식 함양에 많은 도움이 되고 있습니다.감사드립니다!

안녕하세요 선생님, 우선 강의 내용과 직접적으로 관련된 질문이 아니라 죄송합니다. 댓글 관련 오류가 몇 가지 발생해 여쭤봅니다.BoardReadActivity.kt 생략 // 댓글 목록 정보 가져옴 fun getCommentListData(key: String) { 생략 // 댓글 헤더에 댓글 개수 출력 binding.commentCountText.text = commentKeyList.count().toString() 생략 }기존 댓글 2개가 있는 상황에서 새 댓글을 1개 입력하면 댓글 개수가 3이 되어야 하는데요,2(기존) + 3(기존2업뎃1) = 5(누적)로 출력이 됩니다.또한 방금 막 작성한 댓글 a의 수정 페이지로 넘어가면추가된 댓글이 즉시 반영되지 않아 맨 위 댓글인 user1이 불러와지며댓글 a가 아닌 맨 위 댓글이 수정됩니다.마찬가지로 a를 삭제하려해도 user-1이 불러와지며삭제되는 댓글도 a가 아닌 user-1입니다.수정과 삭제를 반복하면 댓글 카운트는 계속 늘어나고, 이 과정에서 앱이 죽기도 합니다.게시글을 한 번 나갔다 들어와야 댓글 수가 제대로 카운트 돼서 어떻게 해야 할지 도움 요청드립니다. 코드 전체는 깃허브에 업로드 해 놓았습니다. https://github.com/shinyelee/my-solo-life

안녕하세요~ 태원님강의 7분42초 쯤에 같아도 빼는 이유가 이해가 안됩니다...public int solution(int num, int sumResult, int[] arr) { int answer = 0; int sum = 0; int lt = 0; for(int rt = 0; rt < num; rt++) { sum += arr[rt]; if(sum == sumResult) { answer++; } //같아도 빼야함 while (sum >= num) { sum -= arr[lt++]; if(sum == num) answer++; } } return answer; }while에 해당하는 내용 입니다.감사합니다.

안녕하세요 강사님!!항상 궁금했던점인데css는 외워야하는건가요?

npm run serve 시, Module not found: Error: Can't resolve '@vue/composition-api' in~~ 오류가 뜹니다.어떻게 해결하면 될 지 알려주실 수 있을까요..

그럼 @RequestMapping(”..”)의 컨트롤러는 스프링 MVC중에서 4의 과정에서 호출이 되는 것인가요?RequestMappingHandlerAdapter 클래스에서 handle()이라는 메서드는 없었는데, 제가 잘못 이해한 것인가요?

public int getNumber(int num, int sumResult, int[] arr) { int answer = 0; int sum = 0; int pi = 0; int i = 0; while(pi < num) { sum += arr[pi]; if(sum > sumResult) { pi = i++; sum = 0; } else if (sum == sumResult) { answer++; } pi++; } return answer; } 채점은 정답으로 나왔는데,,혹시 다른 예외상황이 있을까요...?

int r = 3이라고 하고 원의 넓이를 구하면 28.2743만 출력이 되어 나오는데, float형은 소숫점 6자리까지 출력이 가능하지 않나요? C언어와 C++에서 출력되는 자료형이 다른건가요??

안녕하세요, 상품수정 post controller의 코드를 보다가 궁금한 점이 생겨 질문드립니다.@PostMapping("/items/{itemId}/edit") public String updateItem(@ModelAttribute("form") BookForm form) { itemService.updateItem(form.getId(), form.getName(), form.getPrice(), form.getStockQuantity()); return "redirect:/items"; }해당 메소드의 parameter인 BookForm 앞에 왜 ModelAttribute가 붙었는지 궁금합니다. return "redirect:/items"로 url요청을 할 때 Model을 전달하기 위함인가요? 그런데 [GET]/items 메소드는 form에 대한 data를 필요로 하지 않는 것 같습니다. @GetMapping("/items") public String list(Model model) { List<Item> items = itemService.findItems(); model.addAttribute("items", items); return "items/itemList"; }
