안녕하세요. 주사위 게임에서 if ~ elif 문에서 질문이 있습니다.이미 위에서 tmp를 sort하여 오름차순으로 정렬화한 다음 a, b, c를 맵핑하였는데, 이런 경우에서 밑에 if ~ elif문을 사용할 경우,첫 번째 elif(elif a == b or a == c:)는 이미 위에 포함되어 있는 것 아닌가요? a == c인 케이스는 이미 a == b == c를 가정해야 가능한 경우의 수라고 생각이 됩니다. 다시 말하면, 이미 오름차순 되어있는 상태에서 맵핑을 하여 a <= b <= c가 이미 기정사실화 되어있는 상황에서 왜 강의에서와 같은 방법으로 코드를 짰는지가 궁급 합니다.따라서, if a == b and b == c : money = 10000 + a * 1000 elif a == b : money = 1000 + b * 100 elif b == c : money = 1000 + c * 100else : money = c * 100이런 방법으로 구조식을 짜는 것이 맞지 않나라는 궁금증이 듭니다.혹시나 제가 생각한 것에서 오류가 있을 경우 지적해주시면 감사하겠습니다. 재밌고 유익한 강의 감사드립니다.  

안녕하세요 강사님 며칠 전 질문에 대한 소스 업로드 하였습니다.스프링 시큐리티 이용시 파라미터 추가되어아래와 같이 addFilterBefore 를 지정하였으나 넘어 가지 않고그냥 UsernamePasswordAuthenticationFilter로 넘어갑니다.왜 안되는지 모르겠습니다..addFilterBefore(authenticationFilter(), UsernamePasswordAuthenticationFilter.class)아래 다른 방법으로 해결하긴 했는데 왜 안되었는지 궁금하네요.

정의 12에서 Matrix A의 pivot columns는 Col A의 Basis라고 배우는데그렇다고해서 (Reduced) Echelone Form A의 pivot columns가 Col A의 Basis는 절대 아니라고 강조하셨잖아요? (32:39)그런데 형태만 보면 Reduced Echelone Form A의 pivot columns는 Col A의 standard basis라고는 말할 수 있어보이는데 만약 Reduced Echelone Form A의 pivot columns는 Col A의 'Basis다'가 아니라 'standard Basis'다 라고 말하면 이것은 맞는 거라고 할 수 있나요?

안녕하세요! part1,part3는 완강하고 part2들으면서 알고리즘 문제풀이 및 부족한 C++지식 보충하며 공부하고 있는 수강생입니다 !다름이 아니라 조금씩 게임사 채용이 올라오기 시작하여 조급한 마음이 생겨 방향성에 대해서 질문드리게되었습니다. 보통 게임사에서 채용을 클라이언트 개발자 , 서버 개발자 , 엔진 개발자로 크게 나눌 수 있는 것 같은데 , 클라쪽은 강사님의 어떤어떤 강의 , 서버쪽은 무슨강의 , 엔진 쪽은 무슨강의를 집중적으로 준비해야 하는지 분류해주시면 감사하겠습니다. 전에도 비슷한 질문을 드렸던 것 같은데, 저는 개인적으로 클라쪽 개발자를 준비하고 싶은데 그렇다면 Part2 DirectX를 집중적으로 준비하면 클라이언트 개발자 취업을 위한 충분한 준비가 되는지가 궁금합니다. 또한 게임개발자 준비자의 포트폴리오라는 것은 단순히 블로그에 스스로 공부한 내용들을 정리한 것 이외에도 추가적인 포트폴리오가 필요하다고 하는 것 같은데, 직무별 (클라 ,서버 ,엔진)로 어떤 포트폴리오를 준비하는 방향으로 가야할 지 알려주시면 정말 감사하겠습니다. 항상 좋은 강의 감사합니다 !

안녕하세요. 멀티 프로세싱으로 병렬적으로 처리하면서 동시에 하나의 프로세스에서 멀티 쓰레드를 통해 동시적으로 처리할 수 있다고 강의에서 넌지시 말하시고 넘어가셔서, 혹시 파이썬으로 ProcessPoolExecutor안에서 ThreadPoolExecutor를 사용하려면 어떤식으로 코드를 짜야할까요??

안녕하세요.강의 후반부 스프링 없는 순수한 DI 컨테이너로 메서도 호출을 한다면, 계속해서 객체를 새로 생성하는 예시를 보여주는 부분이 있습니다.여기서 궁금한 것은 AppConfig에 @Configuration 과 해당 클래스 메서드들에 @Bean 설정이 되어있는데, 이것들은 순수한 DI 컨테이너에서 의미없는 어노테이션들이 맞을까요?원래는 빼야하는데 그냥 안빼시고 설명하신 것 인지 궁금합니다.

저는 아래와 같이 nx가 7이 될때 return을 해줘야 한다고 생각했습니다.왜냐하면 distance 배열에서 거리를 입력하는데, 7,7에 도착하는 순간 return을 한 그 순간의 값이 최단경로의 길이라고 생각했습니다.return을 해주지 않는다면 distance[7][7]의 값이 최단 거리가 아닌 가장 긴 거리의 값으로 덮어써 진다고 생각을 했는데, 왜 (nx ==7 && ny == 7)경우 return 하게끔 예외처리를 해주지 않아도 되는지 궁금합니다. for (int i = 0; i < 4; i++) { int nx = x + dx[i]; int ny = y + dy[i]; // if (nx ==7 && ny == 7) { // distance[nx][ny] = distance[x][y] + 1; // answer = distance[nx][ny]; // return; // } if (nx >= 1 && nx <= 7 && ny >= 1 && ny <= 7 && board[nx][ny] == 0) { // 범위 안이고 해당 좌표의 값이 0 일 경우 board[nx][ny] = 1; distance[nx][ny] = distance[x][y] + 1; queue.offer(new Point(nx, ny)); } }

안녕하세요! 질문이 있습니다.if (ch[i] === 0) {ch 배열을 만드는 것말고if (tmp.indexOf(arr[i])) {저는 이렇게 조건을 주었는데 안되더라구요! 왜 이 방법은 안되는지 궁금합니다..!

dashboard 2.0 설치중인데요kubernetes-dashboard-token--뒤에서 tab을 눌러도 자동완성이 안되고동영상 학습과 같은 값을 임의로 넣어봐도 안됩니다.어떻게 해야 할까요?tab은 수십번 눌러봤습니다.맨 앞에 kubectl 부분에서 ctl 지우고 kube에서 tab을 누르면 자동완성이 나오는데kubernetes-dashboard-token- 여기에서는 아무리 눌러도 자동완성이 안되네요

말씀해주신 것처럼 사용자 계정도 영문으로 만들었고파이썬도 잘 다운받았고vs code 내에서도 파이썬 다운을 받았는데Interpreter 인식이 안됩니다.어떻게 해야 해결할 수 있을까요?

강의시간 11:26위 상황은 jsession 쿠키를 제거한 상태에서 remember-me쿠키만 지닌채 서버로 요청한 상황입니다.jsession이 없기 때문에 securityContextHolder 에서 getContext() 로 찾을 수 있는 securityContext객체가 없기 때문에 getContext( )의 결과는 null 이지 않을까...?위의 물음에 잘못된 점이 있는지 궁금합니다.

안녕하세요 오랜만에 학습하다 궁금한점이 있어 문의 남깁니다. razor 페이지에 변수를 선언해 해당 값을 화면에 보여주는 작업을 할 시 사이드바를 통해 다른페이지로 이동했다 돌아오면 변수가 없어지게 됩니다. 이를 해결하기 위해 클래스를 선언 후 해당 클래스를 종속성 주입을 통해 해당 클래스 내부의 변수를 사용하는 식으로 해결했는데 이 방법이 정석적인 방법인지 궁금합니다. cs파일의 클래스를 통해 함수를 구현하는데 해당 함수에서 다른 razor페이지에 직접 접근해 데이터를 화면에 뿌리는 방법이 있는지 궁금합니다. 현재는 방법을 찾지 못해 cs파일을 사용하지 않고 해당 함수 내용을 razor 파일의 code 부분에 해당 함수 내용을 구현해 사용하고 있습니다. 배열에 값을 입력하고 입력되는 값들을 화면에 보여주기 위해 StateHasChanged() 를 사용해 보여주었는데 해당 페이지에서는 잘 동작을 하는데 다른 페이지로 이동 후 다시돌아오면 StateHasChanged()가 작동하지 않습니다. 디버그 확인해보니 페이지를 이동했다 와도 배열에 값을 정상적으로 삽입이 됩니다. 다른 이벤트(버튼 클릭) 등이 발생하면 화면에 보여주는 작업이 동작하는데 StateHasChanged()로는 동작 안하는게 이해가 안갑니다... 디버그 모드로 확인 시 StateHasChanged를 수행하기는 하는데 화면에는 변화가 없습니다. 이런경우가 있나요? 항상 감사합니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]안녕하세요 김영한님! 강의 항상 잘듣고 있습니다!다름이 아니라, 스프링 역사이야기를 듣다보니, 궁금해져서 아래 링크(스프링부트 페이지)로 확인해보았습니다. https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.7-Release-Notes그러던중, 현재 스프링부트는 2.7 까지는 안정적이게 나와있는 것을 확인하였고, preview 로 3.0 버전이 나온것 까지는 알게 되었습니다. 하지만, 여기서 궁금했던것은 v2.7 다음 버전이 v2.8이 아닌 v3.0인것으로 보이는데, 이게 왜 이렇게 뛰는 것일까요? ,기존 spring boot 2.X -> Spring boot 3.X 변경되는 점이 많아서 그런건가요? 

회사컴퓨터에서 강의를 듣다가 노트북으로 코드를 옴겨왔는데 갑자기이런 에러가 나네요 구글링을 해보니 접근권한 혹은 이미 사용중인 포트라고 하는데켜진 로컬호스트 포트중엔 3090이 쓰이는건 없었습니다.
