Beauty Contest http://poj.org/problem?id=2187 题目描述:输入n对整数点,求最距离远的点对,输出他们距离的平方和 算法:拿到这个题,最朴素的想法就是用2层循环遍历所有的点对,但这样可能会超时.由于距离最远的点对必定在点集的凸包的顶点上,所以只用遍历凸包上的点对就行.这样就把可能存在的大量的点给排除.哈哈~~~还是凸包. #include <iostream> #include <algorithm> #include <iomani…

题目链接:http://poj.org/problem?id=2299 题目大意:给定n个数,要求这些数构成的逆序对的个数. 可以采用归并排序,也可以使用树状数组 可以把数一个个插入到树状数组中, 每插入一个数, 统计比他小的数的个数,对应的逆序为 i- getsum( data[i] ),其中 i 为当前已经插入的数的个数, getsum( data[i] )为比 data[i] 小的数的个数,i- getsum( data[i] ) 即比 data[i] 大的个数, 即逆序的个数.最后需要把…
