Nice solution. I am writing in C#, myself. I def. had to start with a more fleshed-out solution and work my way down to this. I wonder if a lengthier solution would be more communicative of the imposed requirements. I pushed mine up as a one-liner, though.

Great Solution.........

Got some fun with Java 8:

Arrays.stream(new int[n]).map(i-> in.nextInt()).map(g -> (g >= 38 && g % 5 >=3) ? g+5-g%5 : g).forEach(System.out::println);

Can anyone explain me how it is printing grade for the values like 67.

A simple and perhaps readable solution.. You can use n instead of temp as it's dummy..

int main() 
{
    int n,temp;
    cin>>temp;
    while(cin>>n)
    {
        if(n<38)
            cout<<n<<endl;
        else if(n%5 >= 3)
            cout<<n+ (5-n%5)<<endl;
        else
            cout<<n<<endl;

    }
    return 0;
}

Python3 one-liner:

grades = [int(input()) for __ in range(int(input()))]

[print(g+5 - g%5 if g%5 > 2 and g>37 else g) for g in grades]

I knew I would find something much shorter than my code here but wow! Nice work!

Your code does not working out in the editor.

but this code should round off 67 as 67%5 is 2 which is less 3 . Help me undertand this please.

Wow! Clearly beatiful and cleanest way I've seen so far

Neat !

i dont understan java .. bt i understood the logic .. thank you:)

I've got a pretty sick one-liner too for C++ can your boy get some upvotes =D

for (int i = 0; i < grades.size(); i++){int nearest5Multiple = 5*((grades[i]/5)+1);if (grades[i] >= 38 &&(nearest5Multiple-grades[i]) < 3 ){grades[i] = nearest5Multiple;}}return grades;

it looks good,but keeping result of (grade%5) in a variable could save you from calculating it two times :)

actually not , as it will work for 41,42 . as 41 % 5 =1 , but we want to have the for 43,44. that goes for all the cases.

Great.

Python - 2 liner

grades = [int(input()) for x in range(int(input()))]
print('\n'.join(map(str,[(i-(i%5)+5) if (i>=38 and i%5>2) else i for i in grades])))

It works

This is my solution

static int[] solve(int[] grades){
        // Complete this function
        for(int i=0; i<grades.length; i++){
            if(grades[i]>=38 && grades[i]%5>2)
                grades[i] = grades[i] + (5 - (grades[i]%5));
            
        }
        return grades;

if (grade > 37){ int newGrade = grade; for (int i=1; i<=2; i++){ newGrade++; if(newGrade%10 == 5 || newGrade%10 == 0){ grade = newGrade; return grade; } } } return grade;

won't work for grade =73 since 73%5 is 3

I achived useing my own implementaion upto 20 lines to achieve this code.But your solution is just awe.I will adopt for this technique.Thank you.

nice logic ..

Even my mobile has 4GB ram.

Python 3 , 3-liner

for _ in range(int(input())):
    g=int(input())
    print(g if g < 38 or g % 5 < 3 else g+(5-(g % 5)))

awesome.

Amazing. Bravo!

Your solution is bad for the problem as it is today. You are printing the elements, but the problem, at least today, says you should return the array. If you do the assigning to the array in one line then it is not possible to check when to assign, so you will always assign, which will be much slower. For this reason i will have to give a downvote to your answer. Still pretty cool for a problem that ask to print them instead of returning, tho

this soluation will not pass all test cases

Get some fun with Python 3::

return [n if n < 38 or n % 5 < 3 else (n + 5 - (n % 5)) for n in grades]

This is brilliant! @cakerusk

This will not work for inputs like 70, 80...

int s=grades.size(); List list = new ArrayList();

for(int i=0;i<s;i++){
    int N=grades.get(i);
    if(N>=38){
  int number =N%5;
   int l = 5-number;
    if(l<3){
        N=N+l;
        list.add(N);
    }else{
    list.add(N);
    }
    }else{
        list.add(N);
    }
}
return list;
}

awesome use of the modulo operation

this is such a clever solution great mind...

it is not working it is giving me error unsupported operand type for %: list and int. can any help me? there compiler is not working correctly, i have run this code in python 2 in my system it is working fine but not in here

new in python can u help me with this code

#!/bin/python

import sys

def solve(grades):
    r=[]
    y=0
    d=0
    # Complete this function
    for i in range(0,len(grades)-1):
        if(grades[i]>=38):
            y=grades[i]/5
            d=5*(y+1)-grades[i]
            if(d<3):
                r[i]=5*(y+1)
            else:
                r[i]=grades[i]
        else:
            r[i]=grades[i]
    return r
               

n = int(raw_input().strip())
grades = []
grades_i = 0
for grades_i in xrange(n):
    grades_t = int(raw_input().strip())
    grades.append(grades_t)
result = solve(grades)
print "\n".join(map(str, result))

Great solution!

neat

heres the same solution in PHP

function solve($grades){

for ($i=0;$i <= sizeof($grades); $i++){
    if ($grades[$i] >= 38){
        if ($grades[$i] % 5 == 3){
            $grades[$i] += 2;
        }
        else if ($grades[$i] % 5 == 4){
            $grades[$i] += 1;
        }
    }
}
      
    return $grades;
}

A difficult and intricate solution with only one line and no conditionals (nor variables).

print . ((uncurry (+) .) . ((. ((*) . fromEnum)) . flip second) <*> (uncurry ((. (>) 3) . (&&) . (<) 37))) . ((,) <*> (flip mod 5 . negate))

fantastic. Such simple logic!!!

You can just group 1st and 2nd if condition into single if condition

Wow that's short!

Short and sweet unlike mine lol

function gradingStudents(grades) {
    // Write your code here
    let finalGrades = new Array(grades.length);
    for (let x = 0; x <= grades.length - 1; x++) {
        if (grades[x] >= 38 && (grades[x] + 2) % 5 === 0) {
            finalGrades[x] = grades[x] + 2;
        } else if (grades[x] === 99 || (grades[x] >= 38 && (grades[x] + 1) % 5 === 0)) {
            finalGrades[x] = grades[x] + 1;
        } else {
            finalGrades[x] = grades[x];
        }
    }

    return finalGrades;
}

Totally forgot about the map method too.

My JS solution:

function gradingStudents(grades) {
	let finalMarks = [];
	grades.forEach(grade => {
		grade < 38 || grade % 5 < 3 ? finalMarks.push(grade) : finalMarks.push(Math.ceil(grade/5)*5)
	})
	return finalMarks;
}

Can someone explain why he substracts the (n % 5) from 5 in line 3?

Thanks, this question should be re-written :/

there is no need for else statment BTW but nice code and true anyway

I can not understand this code can you explain please, i know how maps works but i dont understand how is this returning every index without loop :D
