I wrote Codeton4 on my old account, that was good. I solved 4 problems, they were pretty good! But Codeton5... Bruhh! I solved D, that was amazing, but not B! C and D without B, that was unexpected. B is to hard to be B and geometry at E was not pretty one! Codeton4 was good:) Codeton5 was bad:(
Actually, you can solve E without knowing geometry. Also B was quite simple, if you know what '|' means
