There are 137 teams that have solved at least one problem. From the number of accepted solutions problems J (125

accepted) and E (112) are the easiest problems. Then there is a notorious jump in complexity and we have

problems M (19) K (18) A (17).

So far there are three problems that haven't been solved by any team: H I N


Unfortunately, it was detected that some official teams committed fraud. This is inadmissible in any type of competition. Competitors invest a lot of time and sacrifice a lot to get there and to obtain a good result. It is not fair that others take the easy way. Especially in the ICPC and in the Caribbean Competitive Programming Community this is unacceptable and will not be tolerated. The teams involved were:

  • Alpha Code
  • System Breakers
  • Team Cali
  • KI-MANES
  • LCD

These teams have been cancelled from the 2021 Qualifier at icpc.global and removed from the standings. Also, the involved contestants will be banned from the next ICPC official competition cycle (2022 Qualifiers and the 2022 ICPC Regional contests).
