Hello Codeforces. Next July, 8th and 9th will take place the OII 2023.

The Ibero-American Olympiad in Informatics (OII) is an annual programming contest for young students enrolled in a high school from Ibero-American countries. Students compete on an individual basis, with up to fifteen students competing from each participating country. The competition has only one round, which happens around June-July each year, and is done online. Students are typically given four problems of algorithmic nature, which they have to solve in five hours.

The competition changed its name in 2022 to Olimpiada Iberoamericana de Informática (OII). If you want know more about this competition, please visit the official web site. Well, I just want to know which are the contestants from each participating country.
