Day 0 没有直达焦作的飞机,所以选择了先到新郑机场,再转乘城际列车.城际列车猜是专门给学生开通的吧,每天只有来和回一共两趟(所以机票选择的余地也不多).买的时候只有无座票了,本来以为会一直站着,但上车才发现是只在卖无座票,而新郑机场是首发站,所以随便坐就行了,不用担心要给后上车的人让座位的,买了无座票还全程坐着的感觉真爽_(:з」∠)_ Day 1 领衣服(羽绒马甲!纯蓝色没有任何广告!),领餐券(5*3+2*2+1=20元/顿),去了食堂一看,主食居然都是6元8元一份?!尤其是面食,价格低…

第一次参加icpc的比赛,也是第一块奖牌,虽然只是铜,但其实打的已经很好了,稍微差一点就可以摸银了. 之前参加省赛,成为那次比赛我校唯一一个没拿奖的队伍,其实还是一直都有一些心结的,而这段时间和新的队友的组队,虽然新队员的实力比之前的队友抢了很多,但是总感觉配合一直有问题,在比赛前一天的晚上,睡在一个房间里聊了很多话,也算是和队友真正达成了默契吧,所以第二天的现场赛配合的很好. 但是我自己在最近一段时间由于各种原因,其实个人的训练远没有之前那么多了,希望接下来能调整自己的训练,争取能在青岛站给奖…

Day 0 提前5个小时从学校出发,在登机口坐下时,飞机还有1个多小时起飞. 航班准时起飞,到了南京以后直接坐地铁到学校附近(南京地铁票也太精致了吧). 因为天已经黑了,就只在学校附近转了一圈就回酒店了. Day 1 日常迷路.原来南航这么大.原来直升飞机是可以开到学校里面的.原来体育馆和体育中心是不同的地方. 一路上经常有部门纳新的小姐姐,跑过来问我们是不是大一新生,还给我们发宣传单,哈哈哈哈哈哈, 小姐姐也太可爱了吧.队友疯狂暗示想去冒充大一新生qwq. 领到比赛的东西以后就去食堂,菜的种类…

题意:BaoBao正在进行在线考试(都是选择题),每个题都有唯一的一个正确答案,但是考试系统有m个bug(就是有m个限制),每个bug表示为第u个问题和第v个问题你必须选择相同的选项,题目问你,如果你修好了第i个bug,BaoBao最高可以取得多少分. 题目数量1e5BUG数量1e5(真多)答案范围1e5 思路:首先,如果出现了bug,导致{a1,a2,...,an}n个题目必须选择一样的结果,那么最高得分肯定是众数的出现次数.我们发现bug是具有传递性的,如果bug连成了一个环,而且你只修复其…
