Game of Coders 3.0
By Eddard, history, 5 weeks ago, In English

Hello Codeforces! :3

Yesterday, our small community in Mansoura held its traditional contest Game of Coders for the third year. And we are very glad to bring you the contest on Codeforces c:

The mirror contest will be held on Tuesday $$$16^{\tiny{\mbox{th}}} $$$ July 2024 at 19:05 UTC+3.

You will be given 5 hours to solve 13 problems that I have prepared (I hope they are all original). The contest is ICPC style with 20 minutes penalty for each incorrect submission, and problems are not sorted by difficulty, so read all the problems carefully. :3

This is my first time creating a full problemset, and it was a very fun (and exhausting) experience, and I would like to thank the people who I couldn't have done it without:

Hope you enjoy the contest and have fun solving problems. <3

UPD: The editorial (not really, just the codes) is finally out! I'll prepare hints and solutions and edit the blog later, hopefully. :3

    we know that $$$f_x = f_{x-1} + f_{x-2}$$$ and $$$f_1 = s.length(), f_2 = t.length()$$$.

    Let's solve it recursively, let $$$func(x,k)$$$ be the $$$k_{th}$$$ character at string $$$x$$$. if $$$k$$$ if greater than $$$f_{x-1}$$$ we can subtract it from $$$k$$$. otherwise, we know that the $$$k_{th}$$$ character in $$$f_{x-1}$$$.

    Code

    Don't forget to check if $$$x=1, x=2$$$ first.

While the editorial is being made , can you please just release the codes for them and then after a while when the editorial is completed then edit that blog to include the editorial as well
