思路: 主要就是模拟这些操作,用链表果断超时.改用堆栈模拟就过了 #include<map> #include<set> #include<stack> #include<cmath> #include<queue> #include<cstdio> #include<vector> #include<string> #include<cstdlib> #include<cstring>…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=4669 考察对取模的的理解深不深刻啊,当然还有状态的设计····设d[i][j]表示以第i个数结尾,余数为j的取法数,那么在第i个数后加一个数 那么有递推式int yu =(  j *  log10( a[i+1] ) + a[i+1] )%k, d[i+1][yu] += d[i][j] .考虑到这是一个环这样多生成了一个余数,这个余数应该减去,还有++d[i+1][a[i+1]%k]. 贴代码:…
