I am getting runtime error with this code when I submit. I wish it could give more details then just say runtime. Can anyone see if there is anything wrong in this code?

```
class Solution {
public:
vector<int> spiralOrder(vector<vector<int>>& matrix) {
if (matrix.empty())
return vector<int>();
if (matrix[0].empty()) {
return vector<int>();
}
int row = matrix.size();
int col = matrix[0].size();
int siz = row*col;
int left=0, top=0, right=col-1, bottom=row-1, index = 0;
vector<int> myArr(siz);
cout << right << " " << bottom;
while(top <= bottom && left <= right) {
for(int i = left; i<=right; i++)
myArr.push_back(matrix[top][i]);
top++;
for(int i = top; i<=bottom; i++)
myArr.push_back(matrix[i][right]);
right--;
for(int i = right; i<=left; i++)
myArr.push_back(matrix[bottom][i]);
bottom--;
for(int i = bottom; i<=top; i++)
myArr.push_back(matrix[i][left]);
left++;
}
return myArr;
}
};
```
