We know that the teams qualified from ICPC Regional 2019 are already fixed. They are supposed to take part in the World Finals in Moscow. As far as I know, a large number of regionals for 2020 are also finished. So I am interested to know how many persons are there, who qualified for both world finals (2019 in Moscow and 2020). If you know, please comment. Also mention the name of the university and regional if possible.
