Redux's blog

By Redux, history, 4 weeks ago, In English,

Hello. There used to be a tutorial on the Extended Eratosthenes Sieve technique at I'm unsure what happened to it. Does anyone have a backup of either the tutorial or the Codeforces blog on it? If there is an alternative tutorial on the topic, that would also be welcomed as well.
