# 回复
很有可能是cin的锅
因为某谷使用的是虚拟机，\r和\n都是回车，所以cin可能会出问题
其实我也只有51分（不过神奇的是，我的程序正好51行）
```
#include<bits/stdc++.h>
using namespace std;
bool ac_ak=true;
string st;
map<char,int> f;
int num[20];
int nl;
bool ans;
void pre()
{
f['Q']=f['Z']=0;
f['A']=f['B']=f['C']=2;
f['D']=f['E']=f['F']=3;
f['G']=f['H']=f['I']=4;
f['J']=f['K']=f['L']=5;
f['M']=f['N']=f['O']=6;
f['P']=f['R']=f['S']=7;
f['T']=f['U']=f['V']=8;
f['W']=f['X']=f['Y']=9;
}
int main()
{
// freopen("1.in","r",stdin);
// freopen("1.out","w",stdout);
pre();
cin>>st;
nl=st.size();
for(int i=0;i<nl;i++)
num[i]=st[i]-'0';
for(int i=1;i<=4617;i++)
{
cin>>st;
if(st.size()==nl)
{
bool fl=true;
for(int j=0;j<nl;j++)
if(f[st[j]]!=num[j])
{
fl=false;
break;
}
if(fl==true)
{
cout<<st;
ans=true;
}
}
}
if(ans==false) printf("NONE\n");
return 0;
}

@[fyz2006](/user/106590) 我用cin也对了

```cpp
#include<iostream>

using namespace std;
int main()

cin>>n;
t=0;
while(cin>>s)
{
m=0;
b=0;
if(s.size()!=n.size())
m=1;
if(m==0)
{
for(i=0;i<s.size();i++)
{
w=0;
if(s[i]=='A'||s[i]=='B'||s[i]=='C')

@[RDFZchenyy](/user/567610) 没有考虑输出"NONE"的情况。如果没有有效名字则输出"NONE"
