JOI Open Contest 2019

Dear all,

JOI Open Contest 2019 is an IOI-like open competition for students at
schools for secondary education. The main purpose of this contest is
to give Japanese delegations and candidates of delegations an
opportunity for training and practice. But the contest itself is open to everybody.
Everybody is welcome to attend JOI Open Contest 2019!

This year, the contest will be held on 14 July 2019.
There will be 3 tasks. Each submitted source program must be written
in C++ (C++14). Problem statements will be provided both in Japanese

twice (Round 1 and Round 2). Contestants can participate in one of
Round 1 or Round 2 according to their time zone. After Round 2 finishes,
we will open the judging server for one day. Interested contestants can
