Exercise 1.28: One variant of the Fermat test that cannot be fooled is
called the Miller-Rabin test (Miller 1976; Rabin 1980). This
starts from an alternate form of Fermat’s Little Theorem, which states
that if n is a prime number and a is any positive integer less than n,

I was solving this problem:
Given a number, find the total number of divisors of the factorial of the number.
Since the answer can be very large , Print answer modulo (( 10^9)+7).

Attached is a C++ header. I would like you to write what you think of the header and what you would do to improve it. Do you see errors? Do you see places where the design could be better? Does the header follow best practices in C++? What’s missing? Etc.
