안녕하세요 딩코딩코님!알고리즘 강의 잘 보고 있습니다ㅎㅎ다름이 아니라, 교재의 2주차 9번 재귀함수 단원에 팩토리얼 문제의 Java와 JS 답안이 60초 카운트 하는 코드로 잘못 첨부된 것 같아 질문 남깁니다!(우선 답은 파이썬 버전으로 확인했습니다!)좋은 강의 덕분에 개념부터 차근 차근 잘 익혀나가고 있습니다ㅎㅎ 감사합니다!

체크를 하고 띄워보면작업표시줄에 뜨기만 하고 바탕화면에는 아무것도 뜨지 않습니다.레노버 window 11 home 사용 중이구요.다른 분이 이 문제를 올리신 걸 봤는데 AMD 사용하면 일어나는 버그 현상(?) 같은 거라고 답변을 보았거든요.거기에 올려주신 방법들을 찾아보려 했는데 정확히 모르겠습니다.ㅠㅠ하지만 또 Launch in the Running Device tool window 를 체크하고 띄워보면 Manager 통해서 잘 나오기는 하는데, 여기서 궁금한 점이 나중에 배포하는 것까지 문제가 없는지 궁금합니다.코팩님께서 화면이 사라졌다고 느끼는 불편함이 있다고 하셨는데 그거 말고는 문제가 없는지 궁금하구요!답변 부탁드립니다!!

제 컴퓨터에서 프로젝트 관련 플라스크 코드와 그 외 템플릿 등등을 작성했고그 모든 폴더가 있는 전체 폴더를 압축해서팀원에게 넘겼습니다.이후 팀원이 압축을 풀고 똑같이 터미널에서 해당 폴더가 있는 경로로 이동 후,python app.py 명령어와flask run 명령어모두 실행해보았지만 Python 이라는 메시지만 나올 뿐, 실행도 오류 메시지도 출력되지 않고 있는 상황입니다.   설정도 다 맞게 해놨고 제 컴퓨터에서는 잘만 돌아가는데 뭐가 문제일까요...?당연히 팀원도 플라스크 install 했습니다.

GPS 해제하면 subdivision surface 오류 고쳐진다는데 버튼이 없어요,, 어떻게 하면되나요 ㅠ 

업캐스팅 문제 예시 8.자식 클래스에만 있는메서드를 호출하면? 관련입니다.A b = new B(1);b.paint();b.draw();b.specialDraw(); ← 여기가 오류가 난다는 건 이해했습니다.또한, 이 문제 정답 관련해서정답:에러error: cannot find symbol라고 적혀있는 것은 확인했습니다.그런데, b.specialDraw(); 부분 이전까지는 정상적으로 작동을 하니까생성자 of AA10생성자 BB1CD까지는 출력이 되어야 하는게 아닌가 궁금합니다.아니면 b.specialDraw(); 부분 오류 때문에error: cannot find symbol로만 출력되는건지 궁금합니다.

2D 오브젝트 Circle을 만들고 거기에 Video Player를 넣어서 동영상을 재생시키면 위 사진처럼 갑자기 각이 생깁니다. 동영상 재생 전에는 원으로 있다가 동영상이 재생되면 갑자기 n각형으로 변하네요.이거 해결하는 방법 있을까요?

안녕하세요 저는 이제 막 html,css 독학으로 하루에 조금씩 알아가고있는 직장인입니다.크롬으로 개발하는게 중요하다고 해서 크롬으로 열심히 하고 있는데 live server로 html작성한것을 보면 border나 색깔을 적용하면 막 같은 도형들이 많이 생기거나 이상하게 보이는 문제들이 꽤 많이 발생했습니다. 참고 공부하다보니 견디기 힘들어서 엣지로 기본브라우저를 바꾸니 해결이 되었습니다. 크롬으로 계속 하고 싶어서 이 현상을 해결하고 싶은데 원인을 아시는분 계실까요? div#danji-toast라는 만들지도 않은게 실습하면서 만든 것이랑 똑같은 속성으로 만들어져요.
