题意翻译 莫斯科在举办一场重要的有 nn 个不同国家的珂学家参与的国际会议,每个珂学家都只会一种语言.为了方便起见,我们规定一种语言用 11 到 10^9109 的数来描述. 在会议之后的晚上,珂学家们决定去看电影.他们去的电影院有 mm 场电影,每场有两个不同的数字,分别代表配音的语言和字幕的语言.如果一个珂学家能听懂配音,他会非常愉悦:如果能看懂字幕,他会比较满意.如果既看不懂也听不懂,他会很生气. 珂学家们决定去看同一场电影,你必须帮助他们选择一场电影,让愉悦的人最多的前提下,比较满意的人…

想必是个半水题,div2的C嘛 仔细观察,发现排序可做. 怎么排序呢?排啥呢?拿啥离散化,拿啥结构体呢? 仔细思考热静分析,便可得出结论: 以每个人会的语言离散化,把每个电影建结构体后不排序,而是枚举+lower_bound查找(时间复杂度是一样的NlogN,但是排序很难写(并不难)) 然后交了我就崩溃了:140个测试点!CF果然还是CF,心理煎熬啊. 然后就A了…

题目链接: https://www.luogu.org/problemnew/show/CF670C 思路: step-1: 语言的数据范围是10^9,所以我们采取用map离散化,这样就能方便且不MLE地记录每个语言会的人数. step-2: 然后我们再遍历一遍所有场次的电影,记录下最多人能听懂声音的那一场,放在一个ok数组里. 接着再遍历ok数组,记录最多人能看懂字幕的那一场就是答案. Tips: step-2能用sort代替,但实测这样会过不了第125个点,因为那个点数据比较毒瘤.下面的代码…

题面 传送门 思路: 离散化.hash 对于这样一个明显的统计排序的题目,当然轻而易举啦~ 但是!看!语言的编号 a数组和 b数组的值最大在\(10^9\)的级别,所以开个数组来存---That's impossible! 所以我们可以用上离散化(也就是hash) 离散化,我们有两种写法 第一种是自己手码代码 先排序,然后去重,接着用二分一一对应,达到离散化的目的 板子: sort(b+1,b+n+1,cmp); n=unique(b+1,b+n+1)-b-1; for(i=1;i<=n;i++…
