The ICPC Vietnam National 2018 was held recently. It is the prelim round before the ICPC Vietnam Regional 2018.
I think it would be a good practice for teams participating in ICPC this year.
Problems are prepared by:
- Lang Trung Hieu pewpew
- Pham Van Hanh skyvn97
- Trung Nguyen chemthan
- Trung Nguyen I_love_Hoang_Yen (yes we have 2 different Trung Nguyen)
- Le Don Khue beo_chay_so
- Some problems are contributed by some universities in Vietnam.
Edit: It seems you cannot ask clarification on Kattis. You can ask clarification here, I will try to answer.
