A — ok. ↵

C — most interesting↵

D — ↵
O(N^2) — precision issue, AC with biginteger / Slower solution — TL issue↵
↵
E — I don't like this↵
↵
G — straightforward voronoi↵
↵
I — input format..↵
↵
FGHI — TL issue (especially I)↵
↵
J — see model solution. really?↵
↵
K — easy.↵

ICPC WF should keep the level of the problem high. But for this year it seems like a big fail...↵
↵
Too many problems have issues not related to the core solution.
