传送门 •题意 二维平面上有 n 条线段,每条线段坐标为 $(l_i,i),(r_i,i)$: 平面上的每个整点坐标上都可以放置一枚硬币,但是要求任意两枚硬币的横坐标不相同: 问最多有多少条线段可以放置硬币. •题解1 考虑到当 $X=x$ 时,最多有一条线段可以放置一枚硬币: 那么,我们可以从左到右查找最多有多少条线段可以放置硬币: 定义变量 $X$ 表示 $[0,X]$ 位置已放置好硬币: 既然是按照 $x$ 来的,那么我们就需要将所有可能可以放置硬币的线段按照 $l$ 升序排列,如果 $l…

我是铁牌选手 这次比赛非常得爆炸,可以说体验极差,是这辈子自己最脑残的事情之一. 天时,地利,人和一样没有,而且自己早早地就想好了甩锅的套路. 按理说不开K就不会这么惨了啊,而且自己也是毒,不知道段错误也可以是MLE,而且我的内存就是卡了那么一点点,在比赛紧张的状态下人也变傻了吧. 这次的题目难度是两边到中间一次递增的,但是我也不懂榜怎么会那样  A Peak Time Limit: 1 Second      Memory Limit: 65536 KB A sequence of  inte…

传送门 题意: 给出一个序列,你可以将任意一个数移到最前面: 求最少需要移动多少次,可以是此序列变成非递减序列: 思路: 定义 (ai,aj) 为逆序对 ( i < j , ai > aj ), 求出 aj 的最大值,用变量 curMax 存储: 遍历一遍数组,求解 ans: 对于∀ i ∈[1,n] ①如果 ai < curMax , ans++; ②如果 ai == curMax , 那么需要特殊判断: (2.1)如果 ai 之前不曾出现比 curMax 大的数,不需要移动: (2.…

今天我挺有状态的,看过的题基本都给了正解(可能是昨晚cf div3打得跟屎一样,人品守恒,不好意思发题解了),自己也给队伍签了很多水题(不敢让队友写,怕出锅). 最后6题滚了,有点可惜.还差B和K没做出来. B我一眼就知道该怎么做了,推了一会发现相当可做,于是给队友嘴巴完队友写挂了 (有些小细节,比如判0什么的,下面的题解会讲). K有不同区间的做法一眼秒,没有的话就manacher,队友又写挂了 (弟弟们,怎么回事? 今天的训练我留意到一件事情,我跟队友讲题意的时候他们能听懂,但他们跟我讲题意…
