PAUL2 - A conjecture of Paul Erdős (hard)

In number theory there is a very deep unsolved conjecture of the Hungarian Paul Erdős (1913-1996), that there exist infinitely many primes of the form x2+1, where x is an integer. However, a weaker form of this conjecture has been proved: there are infinitely many primes of the form x2+y4. You don't need to prove this, it is only your task to find the number of (positive) primes not larger than n which are of the form x2+y4 (where x and y are integers).

Input

An integer T, denoting the number of testcases (T≤500000). Each of the T following lines contains a positive integer n, where n≤1012.

Output

Output the answer for each n.
