    If anyone has suggestions on how to improve this, please let me know! I'm doing my best to learn how to become an efficient programmer.

    vector<int> rotLeft(vector<int> a, int d) {
    vector<int> a2(a.size());
    for (int i = 0; i < a2.size(); i++, d++) {
        if (d == a2.size()) {
            d = 0;
        }
        a2[i] = a[d];
    }
    return a2;
}
