题目链接:http://acm.hnu.cn/online/?action=problem&type=show&id=12833&courseid=268 解题报告:有个11个月大的程序员写了一个二分查找,想要实现的功能是输入一个数组,数组里面都是100以内的整数,然后输入一个x,如果这个数组中存在大于等于x的 数就输出这个数在数组中的位置,如果没有就输出数组的长度,但是这个代码有bug.现在给出数组长度n,x,还有一个y,y为1的时候让你出一组可以让这段代码得到正确答案的数据,y…

Validate if a given string is numeric. Some examples: "0" => true " 0.1 " => true "abc" => false "1 a" => false "2e10" => true Note: It is intended for the problem statement to be ambiguous.…

2756: [SCOI2012]奇怪的游戏 题目:传送门 题解: 发现做不出来的大难题一点一个网络流 %大佬 首先黑白染色(原来是套路...)染色之后就可以保证每次操作都一定会使黑白各一个各自的值加1 那么我们接着统计一下黑白格子个数cnt1和cnt2,以及各自的权值和sum1和sum2 然后就要分情况讨论了: 1.在cnt1不等于cnt2的情况下   假设有解且最终的数值均为ans,那么不难发现:cnt1*ans-cnt2*ans=sum1-sum2(因为每次操作黑白格子的总和同时加1,所以总…

要点 不难想到gcd一下然后枚举每个开头走一圈,并记录一下数值. 最终答案是分情况的:1.能走几圈走几圈然后加上最后剩余的最大子段和:2.也可能是最后一圈后面的拖后腿了,所以最后一圈没走完就停,即长度为一圈长的最大子段和:3.一圈为负数时只考虑一圈内的即可,多走了反而变差. 求环形的.不超过某长度的最大子段和,用双端队列处理一下前缀和. const int maxn = 1e4 + 5; int T, n, m, k; ll s, a[maxn]; ll calc(vector<ll> v,…
