First let's get your merge fixed. It would be far easier if you didn't
do an in-place merge. For example an interface like this:

vector<string> merge(const vector<string>& left, const vector<string>&
right);

Yes, the above isn't as efficient, but it is a better learning exorcise.
Please consider it.

If you insist on doing an in-place merge, then start with a simple case:

int main() {
    vector<string> v;
    v.push_back("1");
    v.push_back("2");
    merge(v, 0, 1, 2);
    printVector(v);
}

Write the simplest solution you can think of. Then go to the next case:

int main() {
    vector<string> v;
    v.push_back("1");
    v.push_back("2");
    merge(v, 0, 1, 2);
    printVector(v);

    v.clear();
    v.push_back("2");
    v.push_back("1");
    merge(v, 0, 1, 2);
    printVector(v);

}

Post your results and we can go from there.
