Left Rotation

    I saw this problem in Steven Skiena's book, The Algorithm Design Manual. Below is my solution in C++:

    vector<int> rotateLeft(int d, vector<int> arr) {
    int n = arr.size();

    vector<int> a(n);
    for(int i=0; i<n; i++) {
        a[i] = arr[(i+d)%n];
    }
    
    return a;
}
