APS - Amazing Prime Sequence |
Bablu is very fond of Series and Sequences...
After studying Fibonacci Series in Class IX, he was impressed and he designed his own sequence as follows...
a[0] = a[1] = 0
For n > 1, a[n] = a[n - 1] + f(n), where f(n) is smallest prime factor of n.
He is also very fond of programming and thus made a small program to find a[n], but since he is in Class IX, he is not very good at programming. So, he asks you for help. Your task is to find a[n] for the above sequence....
Input
Your code will be checked for multiple Test Cases.
First Line of Input contains T (<= 100), the number of Test Cases.
Next T lines contain a single number N. (1 < N < 10^7).
Output
Single line containing a[n] i.e. nth number of the sequence for each test case.
Example
Input: 3 2 3 4 Output: 2 5 7
