个人认为更抽象的做法
```cpp
#include<bits/stdc++.h>
using namespace std;
char c;
int num[30],ok[105],ans,maxn,minn=0x3f3f3f3f;
int main()
{
while(cin>>c)
{
num[c-'a'+1]++;
}
sort(num+1,num+28);
ans=num[27]-num[upper_bound(num+1,num+28,0)-num];
ok[0]=ok[1]=1;
for(int i=2;i<=100;i++)
{
if(ok[i]!=0) continue;
ok[i]=-1;
for(int j=2;j*i<=100;j++)
{
ok[i*j]=1;
}
}
if(ok[ans]==1) cout<<"No Answer\n0";
else cout<<"Lucky Word\n"<<ans;
return 0;
}
```
