#include <bits/stdc++.h>

void solve()

if (q == "nanjing")
v++;
}
}
num = max(num, v);
auto f = *s.begin();
s.erase(s.begin());
s += f;
}
cout << num << '\n';
}
int main()
{
ios::sync_with_stdio(false), cin.tie(0), cout.tie(0);
int t = 1;
cin >> t;
while (t--)
solve();
return 0;
}
这程序好像有点Bug,我给组数据试试?
