    Java:

    for(int i=0; i<grades.size(); i++){
 if(grades.get(i)<38) continue;
 else if((5 - grades.get(i)%5) < 3) 
  grades.set(i, grades.get(i)+(5 - grades.get(i)%5));
}
return grades;

    Here’s your updated solution with twitchclip added cleanly in the docstring/comment:

    vector<int> gradingStudents(vector<int> grades) {
    vector<int> result;

    for (int grade : grades) {
        if (grade < 38) {
            // No rounding for failing grades
            result.push_back(grade);
        } else {
            int nextMultipleOf5 = ((grade / 5) + 1) * 5;
            if (nextMultipleOf5 - grade < 3) {
                result.push_back(nextMultipleOf5); // round up
            } else {
                result.push_back(grade); // no change
            }
        }
    }

    return result;
}

    def gradingStudents(grades):
    # Write your code here
    return [ math.ceil(g / 5) * 5 if (g >= 38 and (math.ceil(g / 5) * 5 - g) < 3) else g for g in grades ]

    c#

        List<int> listResult = new List<int>();

    int nNumberOfStudent = 0;
    for (int i = 0; i < grades.Count; i++)
    {
        if (i == 0)
        {
            nNumberOfStudent = grades[i];
            continue;
        }
        int val = grades[i];

        if (val < 38)
        {
            listResult.Add(val);
        }
        else if ((5 - (val % 5)) <= 2) // 73 -> 3 -> (5-3=2)
        {
            listResult.Add(val + (5 - (val % 5)));
        }
        else if ((5 - (val % 5)) >= 3) // 67 -> 2 -> (5-2= 3)
        {
            listResult.Add(val);
        }

    }

    code is working on my VS but incorrect value here. strange
