为什么0和1都少一个呢。。 不知道哪错了 哪位大牛帮忙看看啦#include <stdio.h>
#include <string.h>
int occur[101][10];
int main(){
bool v[100];
for(int i=2;i<101;++i){
memset(v,0,sizeof(v));
int t=1;
while((t%=i)&&!v[t]){
v[t]=1;
t*=10;
occur[i][t/i]++;
}
}
int n,k,ret=0;
while(scanf("%d%d",&n,&k)!=EOF){
ret=0;
for(int i=2;i<n;++i) ret+=occur[i][k];
printf("%d\n",ret);
}
return 0;
}
