first Python AC: bitmask moment https://dmoj.ca/src/7057028
Some of my problems
- https://dmoj.ca/problem/xdiagonal my first problem on dmoj, a bit of implementation pain
- https://dmoj.ca/problem/othscc1p4 was meant to be dp until I realized the
solution
- https://dmoj.ca/problem/othscc1p5 could've been a dp and bitmask problem if it had different constraints (and if I knew dp well enough back then)
- https://dmoj.ca/problem/othscc2p4 was meant to be a 15p+ data structure question but the ideas were too template
- data structure test go brrr https://dmoj.ca/contest/othscc3 editorials soon hopefully
