Clever Average Students per Section

For the problem, I determined the solution for visible students per section with the DEMO_TOKEN API key to be 24. I made a GET request to the /v1.1/sections route with a few modifiers (limit set to max and distinct set to return student JSON arrays in sections only).

Using Go, I wrote a struct that takes in the 2D array of data, and logic in my main function that increments an info struct that contains total students and sections. I then return the average of this result.
