About

안녕, 친구들!

제가 틈 날 때마다 하나씩 만든 문제로 Coding Contest를 만들었습니다. 경쟁이 아니라 문제를 푸는 즐거움을 함께 느껴보고자 만든 것들이니 등수는 신경쓰지 마시고 재밌게 풀어주시면 좋겠습니다.

문제를 풀다가 이상한 부분이 있거나 건의할 내용이 있으면 "Discussions"란에 언제든지 말씀해주시면 답변해드리도록 하겠습니다.

또한 조금이라도 도움이 될 수 있도록 editorial도 열심히 작성해 놓았으니 contest가 끝난 후 editorial도 꼭 읽어봐주시면 감사하겠습니다.

Happy Coding!

Each challenge has a pre-determined score.
A participant’s score depends on the number of test cases a participant’s code submission successfully passes.
If a participant submits more than one solution per challenge, then the participant’s score will reflect the highest score achieved. In a game challenge, the participant's score will reflect the last code submission.
Participants are ranked by score. If two or more participants achieve the same score, then the tie is broken by the total time taken to submit the last solution resulting in a higher score
