Grading Students

• Every student receives a  in the inclusive range from  to .
• Any  less than  is a failing grade.

Sam is a professor at the university and likes to round each student's  according to these rules:

• If the difference between the  and the next multiple of  is less than , round  up to the next multiple of .
• If the value of  is less than , no rounding occurs as the result will still be a failing grade.

For example,  will be rounded to  but  will not be rounded because the rounding would result in a number that is less than .

Given the initial value of  for each of Sam's  students, write code to automate the rounding process. Read full question on hackerrank.

Solution in C# -

class Result

{

    public static List<int> gradingStudents(List<int> grades)

    {

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

        for(int i=0; i<grades.Count; i++)

        {

            int x = grades[i]/5;

            x++;

            int y = x*5;

            if(y-grades[i] < 3 && grades[i] >= 38)

            roundedGrades.Add(y);

            else

            roundedGrades.Add(grades[i]);         

        }

        return roundedGrades;

    }

}

class Solution

{

    public static void Main(string[] args)

    {

        TextWriter textWriter = new StreamWriter(@System.Environment.GetEnvironmentVariable("OUTPUT_PATH"), true);

        int gradesCount = Convert.ToInt32(Console.ReadLine().Trim());

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

        for (int i = 0; i < gradesCount; i++)

        {

            int gradesItem = Convert.ToInt32(Console.ReadLine().Trim());

            grades.Add(gradesItem);

        }

        List<int> result = Result.gradingStudents(grades);

        textWriter.WriteLine(String.Join("\n", result));

        textWriter.Flush();

        textWriter.Close();

    }
