wierd error

This code was running well in eclipse but when I tried to compile it online it showed this error.

Exception in thread "main" java.util.NoSuchElementException

at java.util.Scanner.throwFor(Scanner.java:862)

at java.util.Scanner.next(Scanner.java:1485)

at java.util.Scanner.nextInt(Scanner.java:2117)

at java.util.Scanner.nextInt(Scanner.java:2076)

at Main.main(Main.java:15)

CODE :

import java.util.*;

import java.lang.*;

import java.io.*;

class Main

{

public static void main (String[] args)throws IOException

{




    Scanner input = new Scanner(System.in);

    int t=input.nextInt();//the error refers to this line

    int ctr;

    double i;

    while(t!=0)

    {

        ctr=0;

        double n=input.nextDouble();



        for(i=1;i<=12;i++)

            {

                ctr=(int) (ctr+Math.floor(n/5));

                n=n/5;

            }





        System.out.println(ctr);

    }


}

}
