    Python

    def gradingStudents(grades):
    final_grades = []
    for grade in grades:
        if grade < 38:
            final_grades.append(grade)
        else:
            nextMulitpleOf5 = 5 * ((grade//5) + 1)
            if (nextMulitpleOf5 - grade) < 3:
                final_grades.append(nextMulitpleOf5)
            else:
                final_grades.append(grade)
                
    return final_grades

    Jva 15 solution public static List gradingStudents(List grades) { // Write your code here List roundedLst = new ArrayList();

    for(Integer grade:grades){
    int tmp=0;
    if(grade>=38){
      tmp = grade%5;
      if(5-tmp <3){
        grade = grade + (5-tmp);          
      } 
    } 
    roundedLst.add(grade);
}


return roundedLst;
}

    Rust best solution

    If you’re looking for solutions to the 3-month preparation kit in either Python or Rust, you can find them below: my solutions 

    pub fn grading_students(grades: &[i32]) -> Vec<i32> {
    //Time complexity: O(n)
    //Space complexity (ignoring input): O(n)
    let mut new_grades = Vec::new();

    for &grade in grades {
        if (grade < 37) && ((grade % 5) > 2) {
            new_grades.push(grade + 5 - (grade % 5));
        } else {
            new_grades.push(grade);
        }
    }

    new_grades
}
