Hello Codeforces!

I am pleased to invite you to CAMA (Amateur Mathematical and Algorithmic Competition) 2nd Edition. CAMA is a mixed competition of mathematics and informatics founded by Spanish international medallists in said disciplines.

The competition will be split into several divisions to make it a more enjoyable experience for everyone. There will be different categories based on studies (high school and college) and level (basic and advanced). The basic division is intended for those who have never participated in a mathematics or informatics competition before, while the advanced division is focused on contestants who are already veterans.

The contest will take place on the 23rd and 24th of November. More info on our web.

A total prize of 500€ is going to be divided among the winners of all the divisions, with such distribution yet to be determined. More information will be posted in a few days. If you want to stay in touch with everything, join our discord where you can talk to our handsome organizers and even more graceful contestants. You can also register for the contest here.
