## 코딩테스트 문제집
백준 레포에서 확장을 하여 사이트로 만들었습니다. 필터링, 검색 기능도 있으니 깃헙으로 보는 것보다 조금 더 편할 수 있습니다.
https://algorithm.tony9402.com/
## 집단지성 프로젝트
코딩테스트 문제집 확장을 하여 해당 레포에 솔루션 업로드가 아닌 [알고리즘 솔루션](https://github.com/tony9402/algorithm-solutions)에서 PR을 올려주시면 됩니다. 현재 main 브랜치에 merge된 솔루션은 다 이전을 완료했습니다.
현재 Open된 PR 올려주신 분들도 저 레포에 다시 올려주시면 감사하겠습니다.
## 백준 코딩테스트 문제집
❈ 코딩테스트을 준비하시는 분들을 위해 문제집을 만들어봤습니다. ❈
❗️ 주의 ❗️
<b> 알고리즘을 처음 공부하시는 분들은 [알고리즘 설명 링크 모음](./link_for_study.md) 등을 활용하여 알고리즘 먼저 공부하시기 바랍니다. </b>
이 레포는 꾸준히 업데이트를 할 예정이며 문제집 어느정도 완성 후 풀이를 Python, Java, C++ 3가지 언어를 올릴 예정입니다.
**(C++로 먼저 올릴 예정입니다.)**
## 최근 기업 코딩테스트 알고리즘 분류 정리
[바로가기](./CodingTest.md)
최근 기업 코딩테스트에 나왔던 알고리즘들을 정리해보았습니다.
대부분은 코딩테스트를 본 분들에게 들은거라 몇개가 누락되었거나 잘못된 부분이 있을 수도 있습니다.
## 각 알고리즘 문제집
**❗️❗️순번은 알고리즘 공부 순서와는 무관합니다.❗️❗️**
여기에서는 각 알고리즘 개념을 설명하는 것이 없습니다. [알고리즘 설명 링크 모음](./link_for_study.md)
문제 뽑은 기준 : 각 태그에 해당하는 문제(코딩 테스트에 나올 정도) 들을 최대한 많이 뽑고 반드시 풀고 넘어가면 좋은 문제를 체크해놨습니다.
### **❈ 중요❗️❗️ ❈**
이 레포는 **코딩테스트에 나올만한 유형**에 대한 문제를 모았습니다.
알고리즘 유형이 회사마다 다릅니다. 따라서 아래 알고리즘들을 꼭 다 안풀어도 됩니다.
지원하시는 회사에 나오는 **유형에 맞춰** 골라 푸시기 바랍니다.
(문제집에도 추천 문제도 골라 푸셔도 됩니다.)
