"Looking for a challenge ?" — Where to submit your codes

Revision en2, by Sazzon, 2018-10-11 04:35:08

Hello codeforces,

as you may know, the famous book "Looking for a challenge?" is quite beloved by our community, given it has really interesting/hard problems and editorials from problem's writer itself.

Recently I got back to my copy, craving to know if I could solve it entirely. On each question statement, the book gives you a URL for that particular question. The problem is, they are outdated. The last time I tried to upload a solution to that URL, at least it gave me another option to it. But now, this is what we see:

After searching through the web (also here), I couldn't find the site that I once visited, and fortunately I found! Here it is: https://szkopul.edu.pl/

Since some of you do not have a copy yet, the value of the book is in each writer's explanation (which I'm not allowed to make it public) of their question and lastly the questions are public to be solved, I took the time to gather the links to those precious (and freaking hard!! ò.ó) questions:
