LeetCode 149. Max Points on a Line Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 给出一系列点,求解在同一直线上的最多的点数 这个题当然最暴力的方法就是三层循环,但这样解题就没有意思了 那么我们能不能将复杂度减少到两层循环呢。那...

Can you solve this real interview question? Max Points on a Line - Given an array of points where points[i] = [xi, yi] represents a point on the X-Y plane, return the maximum number of points that lie on the same straight line. Example 1: [https://a
Max Points on a Line Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 哈希表法 复杂度 O(N^2) 时间 O(N) 空间, N为点数 思路 应知应会: 平面里确定一条直线要两个数据,可以是两个不同的点(高中数学做法),也可以是一个点加一个斜率(这...
链接:http://leetcode.com/problems/max-points-on-a-line/ 题解: 这道题是旧时代的残党,LeetCode大规模加新题之前的最后一题,新时代没有可以载你的船。要速度解决此题,之后继续刷新题。 主要思路是,对每一个点求其于其他点的斜率,放在一个HashMap中,每计算完一个点,尝试更新global max。
Max Points on a Line@LeetCode Max Points on a Line 题目本身不难,一次AC可能有点困难,因为要考虑的东西还是挺多的。两层循环,外层遍历所以点,内层遍历外层点之后的所有点,同时在内层循环用一个HashMap来保存每个斜率对应的,这样在内存循环中,斜率相同就代表是在同一条直线上了。这里要注意的有两点:...
