It seems that just yesterday I was developing the basic Codeforces functionality and preparing the first round. In fact, 10 years have passed since then. Ten years! Codeforces celebrates an unusual birthday - 10 years is a symbolic and important date. More than 700 rounds and open competitions have been hosted, the number of problems in the archive is close to 6000, more than 60 million submission
