Hi!

I get "Runtime error" with "Last executed input: [0]".

When I run next code on my machine, everything is ok:

```
#include <iostream>
#include <set>
#include <vector>
using namespace std;
class Solution {
public:
vector<int> plusOne(vector<int> &digits) {
int origin = 0;
int degree = 1;
for (int i = digits.size() - 1; i>-1; --i)
{
origin+=digits[i]*degree;
degree *= 10;
}
origin++;
vector<int> result;
if (origin % degree == 0) {
result.push_back(1);
int i = 1;
while (i <= digits.size()) {
result.push_back(0);
++i;
}
} else {
degree /= 10;
while (degree != 0)
{
int integ = origin/degree;
origin = origin%degree;
degree /= 10;
result.push_back(integ);
}
}
return result;
}
};
int main()
{
vector<int> vec;
vec.push_back(0);
Solution solution;
vector<int> res = solution.plusOne(vec);
for (int i = 0; i<res.size(); ++i)
{
cout << res[i] << endl;
}
return 0;
}
```

Class is definitely the same as in my solution.

Compiler: gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)

What is wrong with my code?
