UVALive 5102 Fermat Point in Quadrangle 極角排序+找距離二維座標4個點最近的點,uvalivefermat題目連結:點擊開啟連結題意:給定二維座標上的4個點問:找一個點使得這個點距離4個點的距離和最小輸出距離和。思路:若4個點不是凸4邊形。則一定是端點最優。否則就是2條對角線的交點最優,可以簡單證明一下。對於凸4邊形則先極角排序一下。#include <cstdio>#include <cstring>#include

[LeetCode] Divide Two Integers,leetcodeintegersDivide two integers without using multiplication, division and mod operator.顯然,如果光用減法太慢。讓商為N,那麼需要用O(N)的時間。這裡要求比較苛刻,連乘法都不能使用,所以只能寄希望於二進位操作了。這裡可以把除數表示為:dividend = 2^i * divisor + 2^(i-1) * divisor +
