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…

/** 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…

cf 443 D. Teams Formation(细节模拟题) 题意: 给出一个长为\(n\)的序列,重复\(m\)次形成一个新的序列,动态消除所有k个连续相同的数字,问最后会剩下多少个数(题目保证消除的顺序对答案不会造成影响) \(n <= 10^{5} ,m <= 10^{9} ,k <= 10^{9},a_i <= 10^{5}\) 思路: 直接上题解好了 首先要用栈预处理序列本身,然后考虑处理后的序列 比较头和尾是否能够消除,细节需要处理好. #include<bi…
