**Introduction To Algorithm**

The word **Algorithm** means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results.

**Advantages of Algorithms:**

- It is easy to understand.
- Algorithm is a step-wise representation of a solution to a given problem.
- In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

**Grading Students– Hacker Rank Solution**

**Problem:**

HackerLand University has the following grading policy:

- 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.

**Examples**

- round to (85 – 84 is less than 3)
- do not round (result is less than 40)
- do not round (60 – 57 is 3 or higher)

Given the initial value of for each of Sam’s students, write code to automate the rounding process.

**Function Description**

Complete the function *gradingStudents* in the editor below.

gradingStudents has the following parameter(s):

*int grades[n]*: the grades before rounding

**Returns**

*int[n]*: the grades after rounding as appropriate

**Input Format**

The first line contains a single integer, , the number of students.

Each line of the subsequent lines contains a single integer, .

**Constraints**

**Sample Input 0**

4 73 67 38 33

**Sample Output 0**

75 67 40 33

**Explanation 0**

- Student received a , and the next multiple of from is . Since , the student’s grade is rounded to .
- Student received a , and the next multiple of from is . Since , the grade will not be modified and the student’s final grade is .
- Student received a , and the next multiple of from is . Since , the student’s grade will be rounded to .
- Student received a grade below , so the grade will not be modified and the student’s final grade is .
