题目大意: https://nanti.jisuanke.com/t/34142 有一个弯道抽象成圆的一部分 车子抽象成矩形 漂移过程中矩形上边会与圆的圆心在同一条直线上 以右上点贴着弯道边缘进行漂移 看不懂题意导致几何题没能做出来 我这个替补选手的临时补位真是愧对队友 所幸是模拟赛 英语渣的痛希望四级放过我 车子漂移时 实际上最远点会画出一个圆 如上红圆 那么当角度为如上a角时 轨道宽度此时必须最大 而角度大于a角时 轨道宽度同样必须为最大 根据勾股定理此时 maxw=sqrt( (a+r)*

第一发又超时了... 题目大意:给你n个点,然后给你n-1的数,表示两两距离,然后让你输出n个答案,第i个答案表示从这n个点里面挑i个点,然后这i个点两两之间会有一个距离,答案要求这些距离和的最大值. 第一次思路:n个点,给你距离,我们可以得到在坐标轴上表示n个点的坐标,然后我们可以先设每个点坐标为xi 可以发现:当n>=2的时候 n=2,i=2 距离为x2-x1 n=3,i=2距离为x3-x1 i=3距离为 x2-x1+x3-x1+x3-x2=2*x3-2*x1 n=5,i=2距离为x5-x1

11月23日 大清早,跟着wyb的脚步,早起跑过去听方伟的编译原理,然鹅一点都没听进去,在焦作胡辣汤群里疯狂灌水... 听说焦作那边冷得不行,前一天看天气预报说那边已经是2℃了,都快零下了,然鹅学校里正好都没有厚的衣服.看队友一个披着黑色大衣,另一个全身裹得严严实实,而我只有秋装三件套,外套毛衣T恤衫,我慌得不行,生怕冻死在焦作.... 上动车,迷迷糊糊地晃到了焦作...感觉整辆车上的人都一起下了车?走到南广场却发现,一辆出租车都没有...G1810号高铁给焦作带来了几百只JBer,然后把他们留

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
