In number world, two different numbers are friends if they have a lot in common, but also each one has unique perks.

More precisely, two different numbers $a$ and $b$ are friends if $gcd(a,b)$, $\frac{a}{gcd(a,b)}$, $\frac{b}{gcd(a,b)}$ can form sides of a triangle.

Three numbers $a$, $b$ and $c$ can form sides of a triangle if $a + b > c$, $b + c > a$ and $c + a > b$.

In a group of numbers, a number is lonely if it doesn't have any friends in that group.

Given a group of numbers containing all numbers from $1, 2, 3, ..., n$, how many numbers in that group are lonely?


-----Input-----

The first line contains a single integer $t$ $(1 \leq t \leq 10^6)$ - number of test cases.

On next line there are $t$ numbers, $n_i$ $(1 \leq n_i \leq 10^6)$ - meaning that in case $i$ you should solve for numbers $1, 2, 3, ..., n_i$.


-----Output-----

For each test case, print the answer on separate lines: number of lonely numbers in group $1, 2, 3, ..., n_i$.


-----Example-----
Input
3
1 5 10

Output
1
3
3



-----Note-----

For first test case, $1$ is the only number and therefore lonely.

For second test case where $n=5$, numbers $1$, $3$ and $5$ are lonely.

For third test case where $n=10$, numbers $1$, $5$ and $7$ are lonely.
