E:用二进制表示放的数字,然后状压$DP$。 F:$biset$优化$DP$预处理,乱搞贪心。 ARC 059 D:傻题,存在长的合法子串就一定会存在短的。 E:前缀和优化$DP$。 F:每个长度为$len$的串出现的概率是相同的,求到长度为$len$的方案数然后除$2^{len}$。 ARC 060 D:对$b$分大于根号和小于根号讨论。 E:倍增...

A.Chmax Rush!(枚举)题意:有一个长度为 N的整数序列S。最初,S的所有元素都是0。同时给你两个长度为 Q的整数序列:P=(P_1,P_2,\dots,P_Q)和V=(V_1,V_2,\dots,V_Q)。斯努克希望依次对序列 S执行Q次操作。第i个操…
在实现上可以取出正数的前三大、前三小与负数的前三大和前三小(这里有一种感性的理解,即原式的值取决于数的绝对值大小和数的符号,所以可以这么取),然后直接暴力枚举更新答案即可 #include<bits/stdc++.h>usingnamespacestd;voidsolve(){intn;cin>>n;vector<int>a,b;for(inti=0;i<n;i++){intx;cin>>...
前面四道题都比较简单,后面两道题的题面到现在都没有加载出来。 A - Bridge and Sheets 直接计算就好了。具体而言,使用一个变量记录前面一个木板右端点是哪里,然后在看当前木板的时候,如果中间有空隙就加上,然后接着维护下去就行了。 intN;longlongW,L;intmain(){cin>>N>>L>>W;longlongr=0;longlongans...
