How to study

1️⃣ Try to solve the problem first before watching the video .

2️⃣ Spend at least 30 minutes studying each problem on your own before watching the video.

3️⃣ When studying a problem, you should study it by drawing pictures and tables with pen and paper .

4️⃣ It's very important to research on paper with pen. This is where problem-solving skills develop.

5️⃣ If the problem is not resolved after 30 minutes, watch the video and practice repeatedly until you become familiar with it.


Only in this lecture
Key points.

#1.
Of course, problem solving
Direct implementation

All class videos are divided into sections that explain the solution method for the corresponding problem and sections that demonstrate the implementation of the source code . By solving a variety of problems yourself, you'll cultivate your application skills and prepare for actual tests, leveraging over 12 years of experience teaching the Information Olympiad.

#2.
Problem and answer code
We provide

Before watching the video, be sure to try solving the problems on your own. It's best to spend about 20 minutes on each problem and, if you can't solve it, watch the video instead. (Watch the first 10 or so problems directly to familiarize yourself with them.)

    컴공으로 학부를 졸업했지만, 1부터10까지의 합도 제대로 못짜는 수준이었습니다. 그런데 김태원 선생님을 만나고부터 기초를 확실히 다질 수가 있었어요! 근데 강의 보면서 충분히 혼자 다른 문제를 통해서 복습해야하는데,, 다른 인적성 공부나 자격증 공부에 치중하다보니 많은 시간을 알고리즘 자습에 할애하지 못했던 점이 스스로 아쉽네요 ㅠ! 강의만큼은 정말 좋았습니다. 원래는 프로그래머스 기준 level1도 잘 못풀었는데.. 이 강의를 듣고 level2까지는 풀 수 있더라구요^^ ㅎㅎ 3부터는 스스로 하는 것이 중요한 것 같습니다. 처음에 목표했던 삼성전자는 못갔지만 다른 원하던 기업에 합격해서 취뽀했습니다. :) 이메일로 질문하고, 여기 인프런에서 질문해도 항상 친절하게 잘 답변해주셔서 감사했습니다. ^^ 항상 건강하세요 선생님~~~! +한가지 팁을 드리면 c++ 랭귀지는 따로 추가로 학습하시는 것 추천드립니다. multimap, unordered map 등을 학습하면 어려운 문제도 접근할 수 있더라구요.. 알고리즘도 중요하지만 기본적인 c++랭귀지 학습도 하는 것이 중요한 것 같습니다!

      취업 축하드립니다.^^ 원하신 기업에 들어갔으니 그곳에서도 승승장구하시기 바랍니다.

      코딩테스트 준비를 막 시작하신 분이라면 입문에 많은 도움이 되실 것 같습니다. 강좌를 들으시면서 온라인 저지 사이트에서 배운 내용을 복습하시면 실력이 금방 늘 수 있다고 생각합니다
