Chinese remainder theorem again Time Limit: 1000/1000 MS (Java/Others) Memory Limit: 32768/32768 K (Java/Others)Total Submission(s): 1299 Accepted Submission(s): 481 Problem Description 我知道部分同学最近在看中国剩余定理,就这个定理本身,还是比较简单的:假设m1,m2,…,mk两两互素,则下面同余方程…
根据题目容易得到N%Mi=Mi-a. 那么可得N%Mi+a=Mi. 两侧同时对Mi取余,可得(N+a)%Mi=0. 将N+a看成一个变量,就可以把原问题转化成求Mi的LCM,最后减去a即可. #include<cstdio> #include<algorithm> #include<iostream> using namespace std; typedef long long ll; int K; ll a; int main(){ ll x; while(1){ c…
