这题可以看作POJ 1961 最小循环节的一个简化版本.某补习班广告贴里给出的两个指针的参考解法简直大误. 受POJ 1961的启发,把数组看作字串,观察可知,如果字串全部由循环节构成(包括最后一段是不完整循环节的情况),则字串刨去最后一个字符的最长匹配前缀为最小循环节.而“最后一个字符的最长匹配前缀”即为KPM里的pattern[length -1].所以我们只需按标准KMP算法求一遍失配函数即可. int minimumCycleSection(vector<int> &a) {…

题目链接:http://www.lintcode.com/zh-cn/problem/max-points-on-a-line/# 条件:给一个点数组 目标:求出共线的点的最多个数 实现:时间复杂度--O(n^2) 要考虑的特殊情况是:①有相同点(这个也太特喵隐蔽了)②斜率不存在的点 思路:暴力求解,遍历每一个点,与他之后的点进行匹配,用一个map<double,int>存储斜率对应的个数. 代码: /** * Definition for a point. * struct Point {…

1. Introduction. 1.1 Managed structures that contain strings are a common sight. The trouble is that managed strings are non-blittable. This means that they do not have a single common representation in the unmanaged world. However, there are several…

jcenter() 仓库比 mavenCentral() 仓库快,因此最好将jcenter 放前面,这样下载速度最快. 使用本地软件仓库:repositories { flatDir { dirs 'lib' } flatDir { dirs 'lib1', 'lib2' } } 本地仓库里的jar包的使用方法: dependencies { compile name: 'name-of-jar' } 也可以这样一次性的指定依赖某个目录中全部的jar文件: dependencies { comp…
