안녕하세요 7.3 참조에 의한 인수 전달 강의 듣고 있는데 교수님이 여러가지 리턴 타입에 관한 강의가 앞쪽 강의에 있다 하시는데 찾지를 못해서요 몇번째 강의 인지 알고 싶습니다.

apm setup은 윈도우 용인데 제 개발환경이 맥이라..

안녕하세요 강사님교안 및 1주차 개념강의를 듣고 문제를 보고있는 중인 학생입니다!문제를 봤을때 로직은 알겠으나 아직 c++에 익숙하지 않은지 구현에서 어려움을 겪고 있어서 한문제 듣고 비슷한 문제로 연습을 하고 싶은데 비슷한 문제를 찾는 방법이 있을까요? 아예 기초문제같은경우는 백준내에서 비슷한 문제라는 탭을 제공해주는것 같은데 강의에 있는 문제는 분류를 어떻게 찾아야할지 잘 모르겠어서 질문드립니다!

연습삼아 나라장터의 상단 부분에 셀레니움을 통해 특정 검색어를 입력 후 검색을 실행 하려합니다관련하여, 해당페이지 접속 후 단순히 find.element를 통해 driver.find_element(By.ID,"AKCKwd").sendkeys("검색어")와같이 사용할 수는 없는 것 인지요?

채점 결과 태스트 케이스2~5까지는 정답으로 나옵니다.4개 모두 200ms안에 끝납니다반면에 가장 테스트 케이스 크기가 작을 case1에서는 타임리밋이 뜹니다이유는 무엇이고 해결책은 무엇일까요?import java.util.*; public class Main { static String answer = "NO"; static int N,M; static int[] ch,dis; public void BFS(int t1, int t2, ArrayList<ArrayList<Integer>> arr) { Queue<Integer> Q = new LinkedList<>(); Loop:for(int i = 1;i<=N;i++) { if(ch[i] == 0) { Q.offer(i); while(!Q.isEmpty()) { int tmp = Q.poll(); ch[tmp] = 1; dis[tmp] = 1; if(dis[t1] == 1 && dis[t2]==1) { answer = "YES"; break Loop; } int len = arr.get(tmp).size(); for(int j = 0;j<len;j++) { int n = arr.get(tmp).get(j); Q.offer(n); } } Arrays.fill(dis, 0); } } } public static void main(String[] args){ Scanner in=new Scanner(System.in); N = in.nextInt(); M = in.nextInt(); ch = new int[N+1]; dis = new int[N+1]; ArrayList<ArrayList<Integer>> arr = new ArrayList<>(); for(int i = 0;i<=N;i++) { arr.add(new ArrayList<Integer>()); } for(int i = 0;i<M;i++) { int a = in.nextInt(); int b= in.nextInt(); arr.get(a).add(b); } int t1 = in.nextInt(); int t2 = in.nextInt(); Main T = new Main(); T.BFS(t1, t2, arr); System.out.print(answer); } }

typescript 기초 강의에서 nest를 처음 실행했는데 실행 시 너무 오래 걸립니다..(약 20~30분 정도) windows os에서 실행 햇는데 이유가 있을까요?현재 컴퓨터 사양은 Memory 32G 에 RAM 16 Core 입니다.매번 이렇게 시간이 걸리면 현실적으로 test가 불가능해서 방법을 구하고자 합니다. +추가yarn으로 실행해봐도 비슷하네요..Windows OS에서 WSL 통해서 Ubuntu 환경에서 실행하고 있습니다.

다른 분들의 질문답변을 보다 헷갈려서 질문드립니다.어떤분 질문답변에서host: www.delivery.com IP와 포트 : 200.200.200.2:3000host:www.hungry.com IP와 포트 : 200.200.200.2:3000이와 같은 상황에서는 포트번호가 같아 작동하지 않는다. 포트번호는 응용 계층(즉, OS)에서 관리하는 가상의 개념인지라 같은 포트번호를 두개의 어플리케이션에서 공유할 순 없다. 라고 되어있는데 다른분 질문에서는aaa.com 의 포트번호 100번에 배달의 민족 주문 서비스(하나의 .jar파일 실행이라고 가정)bbb.com 의 포트번호 100번에 카카오 선물하기 서비스(IP는 200.200.200.2 로 동일하다)이런식으로 따로 연결이 되고 이 포트번호 100에는 또다른 프로그램(서비스)을 연결할 수 있다고 되어있습니다. 다른 도메인이 같은 포트를 사용할 수 있는 건지 궁금합니다. 답변주시면 정말 감사하겠습니다. 

안녕하세요 강의에 사용했던 예제 샘플들은 공유 안해주시나요?

혼자 풀어봤을 때, 다음과 같은 코드를 작성하였는데요.타임리밋이 일어날 만한 곳이 while문밖에 없는거같아서 계속 보는데 이유를 모르겠습니다.첫 요소가 K만큼 들어왔으면 그 다음부터는 1번씩만 put하니까 괜찮을 것이라 생각했는데 어떠한 이유로 타임리밋이 뜨는걸까요 ㅠㅠ?public static String solution(int n,int k,int[] arr) { String answer =""; HashMap<Integer,Integer> map = new HashMap<>(); // 매출의 종류 => HashMap & Sliding Window int lt=0; for(int rt = 0;rt<=(n-k);rt++) { while(lt-rt<k&&lt<n) { map.put(arr[lt], map.getOrDefault(arr[lt],0)+1); lt++; } answer += map.size()+" "; if(map.get(arr[rt])>1) { map.put(arr[rt], map.get(arr[rt])-1); }else { map.remove(arr[rt]); } } return answer; }

안녕하세요! 강의자료 요청드립니다. 빅데이터분석기사 필기 1~4 강의 모두 신청하였고, 메일 주소는 choangelina@naver.com 입니다추가적으로, 로드맵으로 구매하여 실기 강의도 함께 구매하였는데요! 시험 일정에 맞게 실기만 4월부터 수강하는건 불가능한걸까요?  감사합니다!

윈도우 환경에서vutual box를 사용하여 kali linux를 올려서 사용하고있습니다...  별도 무선랜 구입없이...윈도우에서 사용하는 무선 랜카드를kali에서 사용할수 있는지요...??

안녕하세요. 강의 6분35초쯤에 나오는 대상 클래스 타입이 무엇을 말하는건가요?

안녕하세요! two sum 리트코드 문제는 인덱스를 리턴하는 건데강의는 True, False를 리턴하는 문제더라구요!문제를 살짝 변경하셔서 진행하신건가요??아니면 문제 링크가 잘못된건가요?!

선생님 composable/alert.js 만들기 전에는 alert창이 잘 뜨다가 아래처럼 했는데 안떠서요~다른 이유가 있을까요?

lettuce와 같은 경우는 락에 대한 재시도가 필요하지 않아도 사용하고,reddisson는 재시도가 필요한 경우 사용한다고 설명들었습니다.그런데 lettuce는 spinLock 기법으로 lock에 대해서 계속적으로 계속적으로 점유하려고 하는 방식으로 설명들었습니다.재시도가 필요하지 않는 lock이라는게, 제가 이해한 것과는 다른 내용일까요?궁금합니다!

안녕하세요. 답변 감사드립니다.전체 코드를 첨부하여 다시 문의글 작성하였습니다.쿠팡 광고상품과 로켓상품도 표기하고자 합니다.if len(link.select(".ad-badge-text")) > 0:print("광고상품")를 아래와 같이 수정하면 될까요?해봤는데 아무표기가 안되서요. if len(link.select("span.badge rocket")) > 0:print("로켓상품") 그리고 광고상품 로켓상품 둘다 표현하고자 하면아래와 같이 표기하면 될까요?if len(link.select(".ad-badge-text")) > 0:print("광고상품")elif len(link.select("span.badge rocket")) > 0:print("로켓상품")광고상품은 광고상품이라고 잘 표기가 되는게 로켓상품은 전혀 결과가 나오지 않아서요.
