Basics / practice / test
Start coding immediately
Practice environment without installation
I recommend this to you
- For those who want to consistently get an A+ in the algorithms/data structures class by preparing beforehand.
- For those who gave up while studying algorithms/data structures because it was too difficult.
- For those who have some experience studying algorithms/data structures, but want to refresh their concepts because they are not clear in their mind.
- For those who need to study algorithms/data structures but don't know where to start or how to study.
- For those who don't know much about algorithms/data structures even though the coding test date is fast approaching.
- For those who are reading the explanation of past coding test problems but are unable to understand due to not knowing the terms.
- For those who have learned coding before entering a gifted high school, but still do not know much about algorithms/data structures.
- For those who are unable to understand the explanations for USACO Silver exam problems due to a large number of unfamiliar terms.
- For those who are able to solve problems that can be solved using only arrays and brute force, but are stuck on problems that cannot be solved with these methods.
I do not recommend it for such people.
- For those who find it difficult to write code that gives the correct answer to a given problem regardless of efficiency.
- For those who think that they need more practice solving problems rather than studying the concepts of algorithms/data structures.
- For those who have sufficient knowledge of time complexity, binary search, trees, hashing, and graphs, etc.
- For those who have already passed the USACO Silver exam.
You can get these things.
- I will be able to understand every problem explanation without any unfamiliar terms.
- I will be able to clearly understand the characteristics and uses of each algorithm/data structure.

1. 체계적인 가이드라인 2. 답변이 빠릅니다. 3. 효율적이고 집중할 수 있게 만드는 친절한 UI 다른 알고리즘 사이트처럼 좋은 문제를 직접 찾아내지 않아도 되는 점이 좋았습니다. 코드트리내에는 좋은 문제들이 있거든요. 4. 문제 답에 퀄리티가 좋음 - 주석까지 친절하게 달아줍니다. 5. 북마크 기능이 있어 부족하게 느껴지는 공부를 일일히 찾을필요없이 편하게 할 수 있습니다. 6. 학생에게 매우 저렴한 가격 - 지금이 기회입니다. 코드트리에서 얻을게 더 많아요. 갓 가성비

어느 정도 코딩테스트를 준비했는데 스킬적인 부분이나 시간,공간 복잡도 관련 개선 부분을 배울 수 있어서 좋은 것 같습니다
