1. 아 각 숫자가 두개씩 들어있는데 딱 한 숫자만 하나 들어있는 배열에서 하나만 든 숫자를 찾는거구나 2~3.  {10, 10, 20, 30, 30, 40, 40, 50, 50, 60, 60} 에선 20이 혼자 {7, 10, 6, 4, 22, 10, 4, 5, 6, 5, 22} 에선 7이 혼자 4. 음 같은 숫자가 두개씩 있는 배열에서 딱 한 숫자만 한개가 들어있으니까 중복을 허용하지 않는 set 자료구조를 사용해보자 5-1. 배열의 각 요소들을 순회하면서 차례대로 set에 넣어보자 5-2. set에 값을 넣을 때 이미 존재하는 값이면 리턴값은 false이다. 5-3. add의 리턴값이 false이면 set에서 해당 요소를 삭제하자 5-4. 모든 요소들에 대한 순회가 끝나면, set에는 딱 1개의 값만 남아있을 것이므로 stream으로 1개의 값을 획득한다. 5-5. 획득한 값을 리턴한다. 6. 즉 제가 제시한 방법의 시간복잡도는 배열의 길이만큼 순회하고, 거기서 다시 논리비교를 매번 하니 O(n²), 공간 복잡도는 O(n)입니다   복잡도가 익숙지 않아서 참 어렵군요  공간복잡도가 헷갈리는데, set에 n개만큼 더했다가 n개만큼 삭제하므로, n²이라고 생각했는데 잘 이해가 안갑니다.공간복잡도는 늘어난 것만 생각하고 줄어드는 것은 고려하지 않나요? 일단 계속 돌려보면서 이해하고 있겠습니당

- 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. ㄴ어디서 문제가 발생한지 잘 모르겠네요. postman url 문제인줄 알고 주소 고쳐봤으나 해결되지 않아서 질문드립니다.

혹시 총 학습시간이 얼마나 되는지 등 알수 있는 방법이 잇을까요? 공부 계획 짜는데 필요해서요!

저도 아래 분과 같이 궁금하네요. 자료가 어디 있을까요?

항상 강의 잘 듣고있습니다! 다름이아니라 곤충 개체 인식관련한 오브젝트 디텍션을 수행하고싶은데, 어떤 모델을 사용하는게 좋을지 여쭤보고싶습니다. 곤충이 한마리만 혹은 다수의 개체가 찍힐 수 있게 영상 촬영 장치를 거치해 두고 곤충이 특정 행동을 했을때 알림을 주는 시스템을 만들고 싶은데요, 강의를 들으면서 Efficient Det을 사용하는게 좋을지 다른 모델을 사용해야좋을지 잘 모르겠어서 질문드립니다. 어노테이션부터 일일히 해야하는데 이런경우 어떤 모델을 사용하는게 좋을까요? 찾아보니 이쪽 분야에서는 Yolo를 많이 사용한다고하긴했지만 정확히 모델간의 차이점이 얼마나 크고 작은지 감이 안잡히네요 ㅠㅠ

버퍼링이 너무 심해서 수강하는데 문제가 있어요 인터넷 환경이 부족한 것도 아니고 다른 스트리밍 사이트 틀어봤지만 아무 문제가 없는데 무슨 일일까요? 다른 날은 전혀 그런 현상이 없었는데 오늘 갑자기 유난히 끊기네요   확인해주세요

선생님이 만든신 웹사이트가서 좋아요를 눌렀을때 다른사람이 좋아요를 눌른게 보이지 않는것같습니다 그리고 로그인하기전에 저가 누른 좋아요가 없어졌어요 카운트가 안되는건가요? 좋아요 누적이랑 여러사람이 눌렀으면 좋아요 4~5 이렇게 숫자로 보여져야하는것같은데 버그인듯합니다 아니면 구현이 안된건가요 ?

@emotion 플로그인을 vue에서도 적용이 가능한가요?

수업 잘 듣고 있습니다. 풀이 보기 전에 작성한 코드인데 반례가 존재하는지 알 수 있을까요? function solution(arr) { let answer = 0; arr.sort((a, b) => { if (a[0] === b[0]) { return a[1] - b[1]; } else { return a[0] - b[0]; } }); for (let i = 0; i < arr.length - 1; i++) { let people = 1; let s = arr[i][0]; let e = arr[i][1]; for (let j = i + 1; j < arr.length; j++) { let ns = arr[j][0]; if (ns >= s && ns < e) { people += 1; } } answer = Math.max(answer, people); } return answer; }

강의를 듣다가 제가 제대로 이해한것인지 의심이 들어서 질문드려봅니다! (1) 실행 context는 선언시점에 결정된다고 알고 있는데요. 그럼 this binding도 마찬가지로 선언시점에 결정되고 실행시점에 참조만 교체되는 논리인가요?  (2) prototype method 의 경우 어떤식으로 this가 binding되나요? 만약 (1)의 논리가 맞다면 프로토 타입에 메소드가 선언될 때, this binding이 일어나야 할 것 같은데, 실제로 프로토타입을 부르는 객체가 결정되기 전까지는  this 에 대한 정보가 없지 않을까요?   좋은 강의 감사합니다 (_ _)

안녕하세요 선생님, SSD 모델로 학습을 진행하고 있는데 생각보다 오탐지(false positve?)가 너무 많이 잡히고 있습니다. yolo에서는 이렇게 잡히지 않았는데... 이유가 궁금하여 지금 학습하고 있는 config file을 길지만 올렸습니다..(죄송합니다) tensorflow의 ssd를 사용했습니다. mmdetection을 사용하면 결과가 또 다르게 나올까요?? focal loss하고 hard example miner 둘 다 확인해봤습니다. focal loss도 똑같이 오탐지를 하면서 단지 학습의 확신을 주는 느낌으로 밖에 안 느껴졌습니다.!!  

xml 파일의 이름이 persistence가 되면 저렇게 xml 양식으로 인식도 안되고 다른 이름으로 하면 인식이 됩니다. 이 jpashop 프로젝트를 생성하니까 이렇게 되었는데 혹시나해서 이전에 수업하던 프로젝트로 가봤더니 똑같은 증상입니다. 구글링 해봐도 이렇다할 해결책을 찾지 못해서 질문드립니다. 아니면 그냥 persistence1.xml로 진행해도 되는걸까요..    

 protected Monster(MonsterType type) : base(CreatureType.Monster)   와 같이 CreatureType을 불러오려고 하면 base에서 보호수준때문에 엑세스할 수 없다는 오류가 뜨는데, CreatureType 설정은 분명히 Public으로 되어있습니다. 이렇게 오류가 뜨는 이유가 뭘까요...?ㅠㅠ 

군대에서 토익 혹은 c언어 공부하려고 마음 먹고 있었는데, c언어를 공부하기로 결정했습니다. 연등을 신청해서 하루에 1~2시간 정도 사이버지식정보방에서 컴퓨터를 이용하여 인강을 듣고, 프로그래밍 연습을 합니다. 그런데 visual studio를 다운 받고 istaller도 하고 하면 컴퓨터를 재시작해야 합니다. 근데 군대 컴퓨터는 재시작 하면 저장파일이 다 사라져서 문제입니다. d드라이브에 넣어서 쓰자니 문제가 생길것 같아서 그렇게는 못하겠습니다. 그래서 구름ide 라는 웹,클라우드 기반 매체를 이용해서 공부하려고 하는데 괜찮을지 궁금합니다.

Querydsl 강의를 듣던 도중, 16강(서브 쿼리)에서 마지막 코드에 대한 질문입니다.   저는 강의를 Kotlin으로 학습하고 있는데요, result의 타입이 `List<Tuple>` 이고, 이 리스트에 있는 각 `Tuple`들에 접근해서 age를 꺼내오고 싶습니다.   `for (tuple in result)`로 하나의 `Tuple`을 순회하며 `println(tuple)`을 해보면, 강의 내용과 동일하게 나오지만,  `println(tuple.get(member.age))` 또는 `println(tuple.get(member.age.avg()))`는 null 이라고 출력됩니다..   `println(tuple.get(member.username))`은 잘 나오는데, age만 null이라고 출력되어 이 age에 어떻게 접근할 수 있을지 궁금해서 질문 남깁니다!!
