Adding the new problem statement.
Adding some notes and the base discussion file for this problem.
Adding a step towards the final solution.  I think I have all the power calculation code working properly.
Apparently the online calculator that I used had an error.  I verified my answer using bc and they matched.
Added the work to sum up the digits but I haven't verified the answer yet.
Verified the final solution and passed.
Adding some timing out of curiosity.  Most of the solutions online relied on language features and internal libraries to calculate the power of 2.
With the printfs commented out, my timing is about 0.001515s (or about 1.5ms).  Doesn't seem too bad given anecdotes of durations taking about a second from online solutions.
