分别用变量记录一下当前是第几个一级标题、第几个二级标题、第几个三级标题，然后每一次增加的时候，就要把比自己等级更小的标题的次数清零。
```cpp
#include <iostream>
using namespace std;
int main()
{
int n;
cin >> n;
int scnt = 0, subcnt = 0, ssubcnt = 0;
for (int i = 0; i < n; i++) {
string op, name;
cin >> op >> name;
if (op == "section") {
// 一级标题，二级和三级就要清零
subcnt = 0;
ssubcnt = 0;
cout << ++scnt << " " << name << endl;
} else if (op == "subsection") {
// 二级标题，三级就要清零
ssubcnt = 0;
cout << scnt << "." << ++subcnt << " " << name << endl;
} else if (op == "subsubsection") {
cout << scnt << "." << subcnt << "." << ++ssubcnt << " " << name << endl;
}
}
return 0;
}
```
