【题解】
链表模拟即可。
1pile不能加s...
【代码】
#include <bits/stdc++.h>
using namespace std;
const int N = 60;
string s[N];
int l[N], r[N];
vector <string> v[N];
int main() {
#ifdef LOCAL_DEFINE
freopen("F:\\c++source\\rush_in.txt", "r", stdin);
#endif
ios::sync_with_stdio(0), cin.tie(0);
while (cin >> s[1] && s[1] != "#") {
for (int i = 2; i <= 52; i++) cin >> s[i];
for (int i = 1; i <= 52; i++) v[i].clear();
for (int i = 1; i <= 52; i++) v[i].push_back(s[i]);
