► Problem açıklaması:
HackerLand University has the following grading policy:
– Every student receives a in the inclusive range from 0 to 100.
– Any grade less than 40 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 grade and the next multiple of 5 is less than 3, round grade up to the next multiple of 5.
– If the value of grade is less than 38, no rounding occurs as the result will still be a failing grade.
grade = 84 round to (85 – 84 is less than 3)
grade = 29 do not round (result is less than 40)
grade = 57 do not round (60 – 57 is 3 or higher)
Given the initial value of grade for each of Sam’s n students, write code to automate the rounding process.
Complete the function gradingStudents in the editor below.
gradingStudents has the following parameter(s):
int grades[n]: the grades before rounding
int[n]: the grades after rounding as appropriate
