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…

今日这场比赛我们准备的题比较全面,二分+数论+最短路+计算几何+dp+思维+签到题等.有较难的防AK题,也有简单的签到题.为大家准备了一份题解和AC代码. A - Meeting with Aliens UVA - 10570 题目意思:让一个成环的序列变成有序的,正序逆序都可以,问最小交换次数. 解题思路:对于一个长度为n的元素互异的序列,通过交换实现有序的最小的交换次数是=n - 被分解成单循环的个数.数据比较小,正着来一遍,反着来一遍,取最小就可以了. #include<iostream>…

赛后总结: T:今天下午参加了答辩比赛,没有给予队友很大的帮助.远程做题的时候发现队友在H上遇到了挫折,然后我就和她们说我看H吧,她们就开始做了另外两道题.今天一人一道题.最后我们在研究一道dp的时候,被疯狂卡时间和内存,也是最后三十分钟开始写的,感觉受到了挫折.┭┮﹏┭┮ J:今天开场一个多小时都在看H,还是没打出来,就换了别的题.彭彭说他打过F,F就交给他了.看了G好久,感觉好像能做,就做出来了(while循环没弄好,T了一次,简直是个傻子).最后看了E和J,打了J,还是wa了,自己想的样例…

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…
