There are $$$O(\infty)$$$ different things that have mentioned in some problem statement on Codeforces and not only it. This is the top of the most interesting and common ones. Place distribution based on my observations
Thanks to creative problemsetters for so various and interesting world of competitive programming problems!
I'd place "love and romance" much higher, since the arrays that Vasya and Tanya give each other because of love seem to appear in every other contest
Fact that there are more crimes than fun in problem statements is quite unnerving
every contest is a war, duh
We will always remember that Igor love Tanya and he wants to show his feelings and write a number on the fence opposite to Tanya's house ^_^
So who can tell me why 'anime girls' is on the top?
don't we all love ourselves beautiful and lovely 2D waifus that will always love us?
About 5% of contests have anime characters in all its problems. Almost always they are young girls. So about 5% of Codeforces problems have anime girls
For example, this round — Codeforces Round 635 (Div. 2) — even with pictures!
How is Chess & (Kings, Knights, Castles, etc.) are different category? Anyways I believe problems statements involving color, flowers, and candies are fun to solve.
next time . cricket!
In one of last contests, Codeforces Round 750 (Div. 2), all problems are about Russian animated series film for children called Luntik
Waifus dominate hehe...
anime boys need love too
