题意: 给出\(n(3 \leq n \leq 1000)\)个数字,求\(max(s_i+s_j) \bigoplus s_k\),而且\(i,j,k\)互不相等. 分析: 把每个数字看成一个\(01\)字符串插入倒Trie树中去,枚举\(i\)和\(j\),然后把\(s_i\)和\(s_j\)从Trie树中删去. 然后在Trie树中贪心找到能与\(s_i+s_j\)异或得到的最大值. 具体匹配的过程中是这样的,首先看树中最高位能否异或得到\(1\). 能的话就往能的那个方向走,否则往另外一个…

题意:M=p1*p2*...pk:求C(n,m)%M,pi小于10^5,n,m,M都是小于10^18. pi为质数 M不一定是质数 所以只能用Lucas定理求k次 C(n,m)%Pi最后会得到一个同余方程组x≡B[0](mod p[0])x≡B[1](mod p[1])x≡B[2](mod p[2])......解这个同余方程组 用中国剩余定理 Sample Input19 5 23 5 Sample Output6 # include <iostream> # include <cst…
