There are hierarchy of class like super class and sub class. Yo have to make sure only one object can be create for any class using new keyword. How you implement the class.

List<Integer> list=Arrays.asList(1,2,3,4,5,6);
Iterator it=list.iterator();
while(it.hasNext()){
System.out.println(it.next());
}
The above code will iterate sequentially through 1 to 6. Can we iterate the same list alternatively so that it will print 1,3,5 without changing the while loop.

You are given an array of length N that contains only integer.

A number in this array is called a special number if it is divisible by at least one other number in the array.

Write a program to print the count of special number of array.

Input format :

First Line - N

Second line - N space separated integer.

Output format :

print the count of special number in the array.

constraints

1<= N <= pow(10,5)

Note - divisible with same number will not considered.

Example -

input

N=3

Array= 5 3 10

output

1

Description - 10 is divided by 5,

5 and 3 are not divided by any number
