preliminary1 Preliminary My team was amazing, and I also solved one for my team. It was a precious experience to solve something that looked complicated by making simpler steps while keeping the O(n) restriction. Though I can't go to the next round due to my age, the experience of today gives me the courage to go on. I want to do more. Thank you, my teammates, and the great professor! 2023. 10. 21. 이전 1 다음
