    Iterative solution with built-in functions 

    int introTutorial(int V, vector<int> arr) {
    auto it = std::find(arr.begin(), arr.end(), V);
    if (it != arr.end()) return std::distance(arr.begin(), it);
    return -1;
}

    Here are my c++ solutions, you can watch the explanation here : https://youtu.be/teDaBhua0bc

    solution 1: 

    int introTutorial(int V, vector<int> arr) {
    for(int i = 0; i < arr.size(); i++) if(arr[i] == V) return i;
    return 0;
}

    solution 2:

    int introTutorial(int V, vector<int> arr) {
    return distance(arr.begin(), find(arr.begin(), arr.end(), V));
}

    function introTutorial(V, arr) {
    return arr.findIndex(element => element === V);
}
