Not sure what’s wrong with this code (JavaScript)

Question

function main() {
var numberVolunteers = parseInt(readLine(), 10)
// Your code here
var x = numberVolunteers%5;
var y = 5 - x ;
console.log(y);
}

Answer 1

I have never seen readLine() use in js but I do come across people on this platform using it ,can you please give me source to read about the usage of readLine()?

Answer 2

its a question in the course exercise.

Volunteers have been divided into 5 groups with equal number of members. If any group has fewer than 5 people, more volunteers must be recruited to fill the positions.
Write a program that takes the number of volunteers and outputs to the console how many volunteers need to be hired to have 5 equal groups.

Sample Input
24

Sample Output
1

Explanation
The nearest number to 24 that is multiple of 5 is 25, so we need 1 more volunteer (24+1=25) to get 5 equal groups.

need to use the modulus moderator % . i entered the coding after //Your code here. but i am trying to see whats wrong with that code

Answer 3

Answer 4

Cheri Yan i am talking about readLine() method in JavaScript since you have tagged Javascript ,I am sure these exercises uses node which allows execution of JavaScript outside browser ,
Here is the only readLine() module I have found in various searches

Anyway assuming readLine() works here in node ,I will see what other error you might be getting

Answer 5

thanks for the link. yes i am assuming the readLine() works, pls let me know if you spot anything. thanks

Answer 6

Cheri Yan
This should work
If you get 0 as remainder meaning the number of volunteers are equally distributed so you don't need to do 5-remainder

function main() {
var numberVolunteers = parseInt(readLine(), 10)
// Your code here
var x = numberVolunteers%5;
if(x!=0){
var y = 5 - x ;
}
else{
var y=0;
}
console.log(y);
}
