csuoj 1392: Number Trick

分析：

给一个小数X，找个A使得：AX=（A循环左移一位）

首先，假设A为一个满足题目条件的数，有n个数位，且最高位数字为A 0 。

那么可列出方程：AX=（A-A 0* 10 n-1 ）*10+A 0————>> A 0 *（10 n -1）=A*（10-X）

也就是说，只要n和A 0 确定了，A也就可以唯一确定。

那么我们只要直接枚举：n=(1->8) A 0 =(1->9)

计算出A是不是满足这两个条件就可以得出正确答案了。

AC代码：

 3 using namespace std;

 5 int power[10],a[10010],ans=0;

 7 ll f1,f2;

10 {

12   while(tmp) tot++,tmp/=10;
13   return tot;

36       f1=(int)tmpx;
37       f2=(ll)10000*(power[i]-1)*j;
38       if (f2%f1!=0) continue;
