各位大佬,我这个已经改到绝望都不知道哪里错了qwq,求助#include<cmath>
#include<cstdio>
#include<bitset>
#define ll long long
#define ri register int
using namespace std;
template<typename TP>inline void read(TP&x)
{
x=0;int f=1;char c=getchar();
while(c>'9'||c<'0'){if(c=='-')f=-1;c=getchar();}
while(c>='0'&&c<='9'){x=(x<<1)+(x<<3)+(c^48);c=getchar();}
x*=f;
}
template<typename TP>inline void print(TP x)
{
if(x<0)x=-x,putchar('-');
if(x>=10)print(x/10);
putchar(x%10+'0');
}
ll prime[66666],size;
bitset<66666>flag;
inline void make_prime(ll x)
{
for(int i=2;i<=x;++i)
{
if(!flag[i]) prime[++size]=i;
for(int j=1;j<=size&&prime[j]*i<=x;++j)
{
flag[prime[j]*i]=1;
if(!(i%prime[j]))break;
}
}
}
ll st[66666][2],cnt;
inline void devide(ll x)
{
for(ri i=1;i<=size;++i)
if(x%prime[i]==0)
{
st[++cnt][0]=prime[i];
while(x%prime[i]==0)
++st[cnt][1],x/=prime[i];
}
if(x!=1) st[++cnt][0]=x,++st[cnt][1];
}
inline ll Pow(ll x,ll y,ll mod)
{
ll ans=1;
for(ll i=y;i;i>>=1)
{
if(i&1)ans=ans*x%mod;
x=x*x%mod;
}
return ans%mod;
}
ll ans=1;
ll a,b;
inline void get_ans()
{
for(ri i=1;i<=cnt;++i)
{
if((st[i][0]-1)%9901)
ans=ans*(Pow(st[i][0],st[i][1]*b+1,9901)-1)*Pow(st[i][0]-1,9899,9901)%9901;
else ans=ans*(st[i][1]+1)%9901;
}
}
int main()
{

make_prime(sqrt(a)+1);
devide(a);
