You have given a list of q queries and for every query, you are given an integer N.  The task is to find how many numbers less than or equal to N have numbers of divisors exactly equal to 3.

Example 1:

Input:
q = 1
query[0] = 6
Output:
1
Explanation:
There is only one number 4 which has
exactly three divisors 1, 2 and 4 and
less than equal to 6.

Example 2:

Input:
q = 2
query[0] = 6
query[1] = 10
Output:
1
2
Explanation:
For query 1 it is covered in the
example 1.
query 2: There are two numbers 4 and 9
having exactly 3 divisors and less than
equal to 10.

Your Task:  
You don't need to read input or print anything. Your task is to complete the function threeDivisors() which takes an integer q and a list of integer of size q as input parameter and returns the list containing the count of the numbers having exactly 3 divisors for each query.

Expected Time Complexity: O(NlogN), 
Expected Auxiliary Space: O(N), where N is min(10^6,N)

Constraints :
1 <= q <= 103
1 <= query[i] <= 1012
