Congratulations to the contestants that made it to world finals!!

I think this was one of the most competed regionals I've ever seen!

I feel like the quality of the problems has been going up in the past 10 years, so congratulations to all of the problem setters as well!

Scoreboard: https://scorelatam.naquadah.com.br/latam-2020/?fbclid=IwAR2L3sSAX_iD4oB01HVewrlnqZpbm4hVw6aEg-u4FOkZ0CutkFbtgLKPuMQ#

Here I give a subjective difficulty to the problems:

• Easy: DLN
• Medium-Easy: CEK
• Medium-Hard: BFHJ
• Hard: AGI
• Very Hard: M

For Mexico solving all of Easy, Medium-Easy and 2 of the Medium-Hard would guarantee pass to world finals.

For other regions solving some/all of the Medium-Hard would also guarantee pass.

Every problem was solved during the contest by at least 1 team, congratulations to the teams that solved the harder problems!

DP was the most common topic it could be used in 6 of the problems, also for all DP problems (except L) they required a non-trivial transformation or optimization.

Notes on M: It was very hard, I think it was comparable in difficulty to https://open.kattis.com/problems/firstofhername. Would recommend finalists to solve this problem.

Link to editorial: https://github.com/Diego1149/ICPC-Latam-2020

For the difficulty in the editorial I assigned it based on the relative difficulty of the contest itself, meaning 1 to the easiest, 10 to the hardest.

Let me know if you have any questions or think I should update any of the editorials!

Hi guys I was trying to filter the scoreboard for code jam based on different things, for example by country, but I couldn't find a way to do it, so I ended up creating a report where I could see all of the information in the scoreboard and apply filters, etc. Link is here

I will continue to update it as rounds start progressing.

You can filter by country, nickname or round (if you ctrl+click you can select multiple things)

I tried to put information which I found useful, let me know what you think!

Edit: Moved everything to 1 page and instead allowed to filter based on round + added round 1B and 1C

Edit2: Added round 2

I was trying to read editorial for round #349 but it's in Russian, so I used google translate to understand it and something funny happened with some of the handles.
