我的思路是用vector申请N行，每一行是一个字符串，结构编译器报错了，求改正后的代码，谢谢。
```c++
#include<iostream>
#include<string>
#include<vector>
using namespace std;
int main()
{
int N;
cin >> N;
vector<string>e(N);
for (int i = 0; i < N; ++i)
{
cin >> e[i];
for (int j = 0; j < e[i].length(); ++j)
{
if (e[i][j] == e[i][j + 1] ==e[i][j + 2])
{
for (int k = j + 2; k < e[i].length() - (j + 2); ++k)
e[k] = e[k + 1];
e[i][e[i].length() - (j + 2)-1]='\0';
}
else if (e[i][j] == e[i][j + 1] && e[i][j + 2] == e[i][j + 3]&& e[i][j + 4] != e[i][j + 5])
{
for (int k = j + 2; k < e[i].length() - (j + 2); ++k)
e[k] = e[k + 1];
e[i][e[i].length() - (j + 2) - 1] = '\0';
}
else if(e[i][j] == e[i][j + 1] && e[i][j + 2] == e[i][j + 3] && e[i][j + 4] == e[i][j + 5])
{
for (int k = j + 2; k < e[i].length() - (j + 2); ++k)
e[k] = e[k + 1];
e[i][e[i].length() - (j + 2) - 1] = '\0';
}
}
}
for (int i = 0; i < N; ++i)
cout<<e[i]<<endl;
return 0;
}
