HackerRank Grading Students problem solution

In this HackerRank Grading Students problem solution , HackerLand University has the following grading policy:

Every student receives a grade 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 grade 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.

Grading Students | HackerRank Solution

Hello coders, today we are going to solve Grading Students HackerRank Solution which is a Part of HackerRank Algorithm Series.

HackerLand University has the following grading policy:

• Every student receives a  grade  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  grade  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  (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.

Function Description

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

Input Format

The first line contains a single integer,  n , the number of students. Each line  i  of the  n  subsequent lines contains a single integer,  grades [ i ] .

Constraints

• 1 <= n <= 60
• 0 <= grades [ i ] <= 100

Sample Input 0

Sample Output 0

Explanation 0

• Student  1  received a  73 , and the next multiple of  5  from  73  is  75 . Since  75 – 73 < 3 , the student’s grade is rounded to  75 .
• Student  2  received a  67 , and the next multiple of  5  from  67  is  70 . Since  70 – 67 = 3 , the grade will not be modified and the student’s final grade is  67 .
• Student  3  received a  38 , and the next multiple of  5  from  38  is  40 . Since  40 – 38 < 3 , the student’s grade will be rounded to  40 .
• Student  4  received a grade below  33 , so the grade will not be modified and the student’s final grade is  33 .

Grading Students

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.
• 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
• 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

Sample Output 0

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 .

HackerRank 'Grading Students' Solution

Martin Kysel · May 12, 2020

Short Problem Definition:

HackerLand University has the following grading policy:

• Every student receives a grade _in__ the inclusive range from _0 to 100 .
• Any grade less than 40 is a failing grade.

Grading Students

Complexity:

time complexity is O(N)

space complexity is O(N)

Follow the problem specification. The solution could be further optimized to remove all unnecessary copies and the whole res array.
