Every Atcoder contest has a color related to it, like for AGC, it is red, and for ARC, it is yellow. For contests between ABC042 to ABC125, it was green, then it turned blue when the number of tasks increased to 6 from 4. Now, the number of problems is 8, color is not chang...

首先,我建议你打ABC。 尽管CF上有很多好题,但如果你想更容易地练习编程,最好去刷AtCoder。 特别地,我推荐做ABC中的B题和C题。做B题可以学到如何更快地写模拟和暴力,做C题可以学到如何想题、如何用草稿纸更快地想出解决方案。 从ABC 042开始,出题人加入了英文题面。目前最新的一场是ABC 125,所以共有84...
