/** Author: Oliver ProblemId: ZOJ3870 Team Formation */ /* 思路 1.异或运算,使用^会爆,想到二进制: 2.我们可以试着从前往后模拟一位一位的^那么只要当前位结果变大便是: 3.一般我们如何利用二进制呢?既然要爆那我们就存1的位置: 4.问题是怎么存,如何用? 5.我之前想的是每个数的每位1都存,但是那样造成的重复计算还没想出怎么避免.看了一下别人的博客,再尝试把每位数的最高位1存起来. 6.想想为什么是存最高位呢: 7.那好,现在是不…

题目传送门 /* 题意:找出符合 A^B > max (A, B) 的组数: 位运算:异或的性质,1^1=0, 1^0=1, 0^1=1, 0^0=0:与的性质:1^1=1, 1^0=0, 0^1=0, 0^0=0: 假设A < B,一定要满足B的最高位对应A的值是0,这样才可能>B(即0^1=1): 然后比赛时假设A的极限是类似0111111的情况,最后假设有误: 题解是先把每个数最高位(1)的位置统计个数,1<<4 的意思是 000010000: 只要与为0,表示最高位p…

题目链接 题意:两个队伍,有一些边相连,问最大组对数以及最多女生数量 分析:费用流模板题,设置两个超级源点和汇点,边的容量为1,费用为男生数量.建边不能重复建边否则会T.zkw费用流在稠密图跑得快,普通的最小费用最大流也能过,只是相对来说慢了点. #include <bits/stdc++.h> const int N = 5e2 + 5; const int INF = 0x3f3f3f3f; struct Min_Cost_Max_Flow { struct Edge { int from…
题意 n个数,找出有几对a.b 符合 a ^ b > max(a,b) .^表示异或号 分析 对于数a,如果它的二进制是: 1 0 1  0 0 1,那么和它 ^ 后 能比他大的数就是: 0 1 X X X X 0 0 0 1 X X 0 0 0 0 1 X 所以对应的b 在a的最高位1到后面第一次出现0之前,都为0,然后在a为0的位置里至少一个为1. 于是就是最高位1的位置有几个数储存下来就可以计算了. 代码 #include<cstdio> #include<cstring&g…

题目大意:n个人,分为两个阵营.现在要组成由若干支队伍,每支队伍由两个人组成并且这两个人必须来自不同的阵营.同时,每个人都有m个厌恶的对象,并且厌恶是相互的.相互厌恶的人不能组成一支队伍.问最多能组成多少支队伍,并在在队伍数最多的前提下求最多的女生数以及输出方案. 题目分析:很显然是个二分图.从阵营1的每个元素向阵营0的每个元素连一条有向边(互相厌恶的不连),这就得到一张二分图.给每条边一个权值,边两端的女生越多,权值越大.只需要求最大完美匹配即可. ps:比赛的时候连边只连了一半儿,导致一直w…

题意:给定N个数,求这N个数中满足A ⊕ B > max{A, B})的AB有多少对.(A,B是N中的某两个数) 分析: 1.异或,首先想到转化为二进制. eg:110011(A)和 1(B)--------A中从右数第三个数是0,若某个数B(eg:110,101,111,……)从左向右数第三个数为1,那么两个异或一定满足A ⊕ B > max{A, B}). 还有哪些数B能让A ⊕ B > max{A, B})呢? 根据上述,同理,从右数第四个为1的数B也符合要求. 很容易想到,将N个…
