I wrote this article just after Edu Round #68 ended.

I participated in this contest and the past contest #573,and I was surprised to find that both of the contests contained problems that are related to games(one) another.Will this kind of problems become a trend in codeforces?

These solutions of this kind of problems may be harder to think,however,they are easier to code.Despite these issues,the problems are really interesting.What do you think about them?
