====== 2024暑期训练第三场加训 ====== [[https://codeforces.com/group/08xATaaemG/contest/541835|比赛链接]] ===== 赛时记录 ===== 这是两人场，开场30min，my签到过了AB，后面想了会C，最后在1h把C过了。后面发现I也是签到，my在1h30min把I过了。这个时候my和fks开始讨论E的做法。觉得E贪心有理有据，用线段树维护就好，然后my开始写E。在2h的时候wa了第一发，开始debug。然后fks把F的做法和my进行了讨论，一开始想了一个topo的做法，但后面证实是假了，写了该做法之后纠结了好久，不想写tarjan或者灭绝树，一直在topo上魔改。然后fks开始写E的对拍，同时my开始debug F，拍出错之后，开始写tarjan，在4h把F过了。然后fks开始想E的dp，my开始写G，在4h30min过了G，随后my开始rush 单调队列优化dp，在4h59min55s 过了E。 ===== 总结 ===== E和F想了假做法浪费了好多时间。 ===== Dirt ===== C(-1):数组开小 E(-1):想了假贪心，应该用dp F(-3):想了假做法，topo是错的
