======2023 牛客暑期多校训练营 6====== =====各题总结===== ====36min | G（-3） + 43min | E==== aytony和max写的签到，G因为情况考虑不周WA了几发 ====107min | C（-2） ==== 统计1到n双阶乘中5的数量，max和white讨论出做法后决定让max用py写（会好写一点） ====185min | H（-1） ==== 对于给定的两个大小为 n的多重集 S 和 T，要求出 S 和 T 的所有子集对的距离和，max用dp两发过掉了（因为对取模考虑不周而WA了一发） ====A(-8) ==== white赛时觉得是对当前最大获利点贪心，实际上要在生成树上进行dp😭 ====总结==== 这场发现A题贪心不过就应该果断舍弃另寻他法，同时要注意简单题的dirt和速度
