    Java:

    // Write your code here

    List<Integer> result = new ArrayList();

    for(Integer grade : grades) {
        if(grade%5 > 2 && grade > 37) {
            result.add(5 * (grade/5 +1));
        } else {
            result.add(grade);
        }
    }

    return result;

    public static List<Integer> gradingStudents(List<Integer> grades) {
        return grades.stream().map(elem -> {
            int module = 5 - (elem % 5);
            return elem >= 38 && module < 3 ? elem + module : elem;
        }).collect(Collectors.toList());
    }

    Here is my c++ solution, you can find video here : https://youtu.be/fYcSakw_5-M

    vector<int> gradingStudents(vector<int> grades) {
    vector<int> result;
    for(int i = 0; i < grades.size(); i++){
        int mo = grades[i] % 5;
        if(mo < 3 || grades[i] < 38) result.push_back(grades[i]);
        else result.push_back(grades[i] - mo + 5);
    }
    return result;
}

    Also python

    def gradingStudents(grades):
    grades = [grade if (grade < 38 or (grade//5 + 1)*5 - grade >=3) else (grade//5 + 1)*5  for grade in grades]
    return grades

    for python

    def gradingStudents(grades):
    for idx in range(len(grades)):
        if grades[idx]>=38:
            if (grades[idx]//5+1)*5-grades[idx]<3:
                grades[idx] = (grades[idx]//5+1)*5
    return grades
