UVA756 Biorhythms crt crt裸题 因为模数已知所以有些值能直接求 #include<iostream> #include<cstdio> using namespace std; typedef long long ll; ll p,e,i,d,lcm=,ans,t; int main(){ ){ cin>>p>>e>>i>>d; ) break; ans=(*p+*e+*i-d+lcm)%lcm; //exgc…

UVA756:https://www.luogu.org/problemnew/show/UVA756 思路 几乎是裸的中国剩余定理模板题 但是需要注意的是此题并不是求最小正整数解 而是求大于d的解 因此对于ans我们需要分类讨论 当ans<=d时 ans=M-(d-ans) 当ans>d时 输出ans即可 代码 #include<iostream> #include<cstdio> using namespace std; **,ans,t; ]={,,,};//存m…

0.引子 每一个讲中国剩余定理的人,都会从孙子的一道例题讲起 有物不知其数,三三数之剩二,五五数之剩三,七七数之剩二.问物几何? 1.中国剩余定理 引子里的例题实际上是求一个最小的x满足 关键是,其中r1,r2,--,rk互质 这种问题都有多解,每一个解都为最小的解加上若干个lcm(r1,r2,...,rk),这个不用我证了吧(-_-||) 解决这个问题的方法是构造法, 先构造k个数 满足, 这样就保证 ,但是由于 bi 乘了除 ri 以外所有 r,所以bi模其它的 r 都为 0, 再把所有 b…

Biorhythms 题意:读入p,e,i,d 4个整数,已知(n+d)%23=p;   (n+d)%28=e;   (n+d)%33=i ,求n .        (题在文末) 知识点:中国剩余定理. /*解释*/ 题解:已知(n+d)%23=p;   (n+d)%28=e;   (n+d)%33=i        33×28×a模23的逆元为8,  则33×28×8=5544:        23×33×b模28的逆元为19,则23×33×19=14421:        23×28×c模3…
