@[小明小红](/user/368346) 现在发现问题了，是每次judge时i没初始化0，但是还是WA了，能帮忙看一下吗？
```cpp
//洛谷CF1B
# include <bits/stdc++.h>
# define ffor(i,name) \
for (auto i = name.end (); i != name.end (); i ++)
# define iter(type) \
type :: iterator
using namespace std;
typedef long long ll;
typedef pair <int, int> pii;
int n, power, sum, i, j, m, ans, t;
string a;
bool judge () {
i = 0;
while (i < m && a[i] > '9')
i ++;
// cout << j << ' ' << i << '\n';
j = i;
while (i < m && a[i] < 'A')
i ++;
return i > m - 2;
}
void print (int x) {
if (x > 26)
print (x / 26);
if (x % 26)
cout << (char) (x % 26 - 1 + 'A');
else
cout << 'Z';
return ;
}
int main () {
ios::sync_with_stdio (0);
cin.tie (0);
cout.tie (0);
cin >> n;
while (n --) {
cin >> a;
m = a.size ();
ans = 0;
if (judge ()) {
power = 1;
for (i = j - 1; i >= 0; i --)
ans += (a[i] - 'A' + 1) * power, power *= 26;
// cout << j << '\n';
cout << 'R';
for (i = j; i < m; i ++)
cout << a[i];
cout << 'C' << ans;
} else {
while (a[j] < 'C')
j ++;
for (i = j + 1; i < m; i ++)
ans = ans * 10 + a[i] - '0';
// cout << ans << '\n';
print (ans);
for (i = 1; i < j; i ++)
cout << a[i];
}
cout << '\n';
}
return 0;
}
```
