이것은 LeetCode의 공식 큐레이팅 된 Top 클래식 인터뷰 질문 목록입니다. 우리의 주요 인터뷰 질문은 다음 시리즈로 나뉩니다.
to help you master Data Structure & Algorithms and improve your coding skills.
데이터 구조 및 알고리즘을 마스터하고 코딩 기술을 향상시킬 수 있습니다.
Just like any other skills, coding interview is one area where you can greatly improve with deliberate practice.
Most of the classic interview questions have multiple solution approaches. For the best practice result, we strongly advise you to go through this list at least a second time, or even better - a third time.
By the second attempt, you may discover some new tricks or new methods. By the third time, you should find that your code appear to be more concise compared to your first attempt. If so, congratulations!
Remember: Deliberate practice does not mean looking for answers and memorizing it. You won't go very far with that approach. The more you are able to solve a problem yourself without any reference to answers, the more you will improve.
다른 기술과 마찬가지로 코딩 인터뷰는 신중한 연습을 통해 크게 향상시킬 수있는 영역 중 하나입니다 .
대부분의 고전적인 면접 질문에는 여러 솔루션 접근 방식이 있습니다. 모범 사례 결과를 얻으려면이 목록을 적어도 두 번째 또는 더 나은 세 번째로 검토 하는 것이 좋습니다 .
두 번째 시도로 새로운 트릭이나 새로운 방법을 발견 할 수 있습니다. 세 번째로 코드가 첫 번째 시도에 비해 더 간결한 것처럼 보일 것입니다. 그렇다면 축하합니다!
기억하십시오 : 고의적 인 연습은 답을 찾고 암기하는 것을 의미하지 않습니다. 당신은 그 접근 방식으로 멀리 가지 않을 것입니다. 답을 참조하지 않고 스스로 문제를 해결할 수있을수록 더 향상 될 것입니다.
