分析: 因为满足任意一组pi和ai,即可使一个“幸运数”被“污染”,我们可以想到通过容斥来处理这个问题.当我们选定了一系列pi和ai后,题意转化为求[x,y]中被7整除余0,且被这一系列pi除余ai的数的个数,可以看成若干个同余方程联立成的一次同余方程组.然后我们就可以很自然而然的想到了中国剩余定理.需要注意的是,在处理中国剩余定理的过程中,可能会发生超出LongLong的情况,需要写个类似于快速幂的快速乘法来处理. 吐槽:赛场上不会快速乘,导致疯狂WA,唉,还是太年轻 代码: #include…

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…
