Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. Example 1: Input: [[1,1],[2,2],[3,3]] Output: 3 Explanation: ^ | | o | o | o +-------------> 0 1 2 3 4 Example 2: Input: [[1,1],[3,2]
题目: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. 这道题需要稍微转变一下思路,用斜率来实现,试想找在同一条直线上的点,怎么判断在一条直线上,唯一的方式也只有斜率可以完成,我开始没想到,后来看网友的思路才想到的,下面是简单的实现:其中有一点小技巧,利用map<double, int>来存储具有相同斜率
给定二维平面上有 n 个点,求最多有多少点在同一条直线上. 详见:https://leetcode.com/problems/max-points-on-a-line/description/ Java实现: /** * Definition for a point. * class Point { * int x; * int y; * Point() { x = 0; y = 0; } * Point(int a, int b) { x = a; y = b; } * } */ class
直线上最多的点数 给定一个二维平面,平面上有 n 个点,求最多有多少个点在同一条直线上. 示例 1: 输入: [[1,1],[2,2],[3,3]] 输出: 3 解释: ^ | | o | o | o +-------------> 0 1 2 3 4 示例 2: 输入: [[1,1],[3,2],[5,3],[4,1],[2,3],[1,4]] 输出: 4 解释: ^ | | o | o o | o | o o +-----------

SVG开发里有个较为少见的问题. 对x1=x2或者y1=y2的直线(line以及path),比如: <path d="M200,10 200,100" stroke="url(#orange_red)"/> 如果,stroke里使用的是渐变效果,那么,在各种浏览器上都会出现同一个BUG,这条线消失了. 原因不好排查,但是道理很简单,参考: www.w3.org Keyword objectBoundingBox should not be used wh
