题目链接 题意:给k对数,每对ai, ri.求一个最小的m值,令m%ai = ri; 分析:由于ai并不是两两互质的, 所以不能用中国剩余定理. 只能两个两个的求. a1*x+r1=m=a2*y+r2联立得:a1*x-a2*y=r2-r1;设r=r2-r2; 互质的模线性方程组m=r[i](mod a[i]).两个方程可以合并为一个,新的a1为lcm(a1,a2), 新的r为关于当前两个方程的解m,然后再和下一个方程合并…….(r2-r1)不能被gcd(a1,a2)整除时无解.   怎么推出的看…

一种不断迭代,求新的求余方程的方法运用中国剩余定理. 总的来说,假设对方程操作.和这个定理的数学思想运用的不多的话.是非常困难的. 參照了这个博客的程序写的: http://scturtle.is-programmer.com/posts/19363.html 这个博客举例说的挺好的:http://blog.csdn.net/mishifangxiangdefeng/article/details/7109217 hdu 3579 Hello Kiki 中国剩余定理(不互质的情况) 对互质的情况…
