本期看点：starmap>recollector
Day 1: T1:我会NTT，*,大样例怎么跑了7.5s，废了...
T2:（看BCD）我会dp（状态数炸了）...（B）我会背包！...
T3:我会暴力!
预计64+30+12=106,废了TT 为什么T1考察选手对树形背包时间复杂度的理解？？！！
Day 2:
T1:我会$\operatorname{mex}(S)=\min(\complement{N}S)$。
T2:我会使用拉马努金之力：观察到{S,a,x},{S,a,y},{S,b,x},{S,b,y}=>(a,x,b,y)的四元环。
T3:我还是会暴力!
预计100+67+12=179,没翻成T_T
