APS2 - Amazing Prime Sequence (hard)

This problem is a harder version of APS.

 

Let $f(n)$ be the smallest prime factor of $n$. For example, $f(2) = 2,\ f(4) = 2$ and $f(35) = 5$.

The sequence $S(n)$ is defined for all positive integers as follows:

  • $S(1) = 0$
  • $S(n) = S(n-1) + f(n)$ (if $n \ge 2$)

Given $N$, find $S(N)$ modulo $2^{64}$.

Input

First line contains $T$ ($1 \le T \le 10000$), the number of test cases.

Each of the next $T$ lines contains a single integer $N$. ($1 \le N \le 1234567891011$)

Output

For each integer $N$, output a single line containing $S(N)$ modulo $2^{64}$.

Example

Input:
5
1
4
100
1000000
1000000000000 Output: 0
7
1257
37568404989
7294954823202325427

Explanation for Input

- $S(4) = 2 + 3 + 2 = 7$

- $S(10^{12}) = 18435592284459044389811 \equiv 7294954823202325427 \pmod{2^{64}}$

Information

There are 6 Input files.

- Input #0: $1 \le T \le 10000$, $1 \le N \le 10000$, TL = 1s.

- Input #1: $1 \le T \le 1000$, $1 \le N \le 10^{8}$, TL = 20s.

- Input #2: $1 \le T \le 200$, $1 \le N \le 10^{9}$, TL = 20s.

- Input #3: $1 \le T \le 40$, $1 \le N \le 10^{10}$, TL = 20s.

- Input #4: $1 \le T \le 7$, $1 \le N \le 10^{11}$, TL = 20s.

- Input #5: $T = 1$, $1 \le N \le 1234567891011$, TL = 20s.

My solution runs in 5.36 sec. (total time)

The source limit and time limit are both reasonable (twice of my ugly code's source length and running time) for solving this problem. Thanks to min_25 for setting those constraints carefully.
