made this after banh_mi;

i have not yet properly solved and/or fully understood solutions to problems I had solved illegitimately, which are as follows: CCC '22 S2, CCC '18 S2, CCC '21 J4, CCC '21 S2, CCC '24 J4, CCC '18 J5, CCC '20 S2.

things really had to go from mindlessly grinding .IO games to I/O problems, didn't they?
