获取属性

$(‘a‘).attr(‘href‘)

class属性

POJ 1328 Radar Installation 贪心题解

本题是贪心法题解,不过需要自己观察出规律,这就不容易了,很容易出错. 一般网上做法是找区间的方法. 这里给出一个独特的方法: 1 按照x轴大小排序 2 从最左边的点循环,首先找到最小x轴的圆 3 以这个圆判断可以包括右边的多少个圆,直到不可以包括下一个点,那么继续第2步,画一个新圆. 看代码吧,应该很清晰直观的了. 效率是O(n),虽然有嵌套循环,但是下标没有重复,一遍循环就可以了,故此是O(n). #include <stdio.h> #include <cmath> #incl

POJ 1328 Radar Installation 贪心难度:1

http://poj.org/problem?id=1328 思路: 1.肯定y大于d的情况下答案为-1,其他时候必定有非负整数解 2.x,y同时考虑是较为麻烦的,想办法消掉y,用d^2-y^2获得圆心允许范围,问题转化为在许多圆心允许范围内取尽可能少的点,也即在许多线段上取尽可能少的点,使得所有线段上都有点被取到 3.从左往右考虑,完全在左边的线段肯定要取点,如果这个点在当前线段上已经取了,明显就可以忽略当前线段,明显在线段上的最优点是右端点 1 #include <iostream> 2
