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?

As we all know,a contest "Technocup 2019-Final" is going to take place this Sunday.However,at the same time,there is also another codeforces round(#543),and it is going to take place just a few hours after the contest "Technocup 2019-Final" will end.Moreover,the name of the coming codeforces round is special! It includes "based on Technocup 2019 Final Round".

So,is it means that the problems that #543 Round is going to have is just the same to the problems that the 2019 final round is going to have? Or,is there a limit of rating or something else to take part in the "Technocup 2019-Final"(that means,not everyone can take part in this contest),and what's the limit?

Is there anyone who know the reason? Thanks a lot to everyone for helping me!!!
