链接:pid=1573">http://acm.hdu.edu.cn/showproblem.php? pid=1573 题意:求在小于等于N的正整数中有多少个X满足:X mod a[0] = b[0], X mod a[1] = b[1], X mod a[2] = b[2], -, X mod a[i] = b[i], - (0 < a[i] <= 10). 思路:中国剩余定理的模板题(全部除数相互不互质版),假设找不到这种数或者最小的X大于N.输出零. 资料:http:/…

数论题,本想用中国剩余定理,可是取模的数之间不一定互质,用不了,看到网上有篇文章写得很好的:数论——中国剩余定理(互质与非互质),主要是采用合并方程的思想: 大致理解并参考他的代码后便去试试hdu上这道题,可还是wa了数遍. #include<cstdio> #define scd(x) scanf("%d",&x) #define sclld(x) scanf("%I64d",&x) #define prd(x) printf(&quo…

Problem Description 要求(A/B)%9973,但由于A很大,我们只给出n(n=A%9973)(我们给定的A必能被B整除,且gcd(B,9973)= 1). Input 数据的第一行是一个T,表示有T组数据. 每组数据有两个数n(0 <= n < 9973)和B(1<= B <= 10^9). Output 对应每组数据输出(A/B)%9973. Sample Input 2 1000 53 87 123456789 Sample Output 7922 6060…
