一个数字取模运算的问题,用C语言怎么实现的呢?

Problem Description
Little Ruins is a studious boy, recently he learned math!

Now he defines f(k) equal the number of prime factors in k, and g(k)=2f(k), he want to know

∑i=1ng(i)

Please help him!

Input
First line contains an integer T, which indicates the number of test cases.

Every test case contains one line with one integer n.

Limits
1≤T≤50.
1≤n≤1012.

Output
For every test case, you should output 'Case #x: y', where x indicates the case number and counts from 1 and y is the result.

Because y could be very large, just mod it with 109+7.
