Asking questions from a list

One of the great things about purrr is you can easily move from having a question about the data to an answer, with just a few lines of code. Here you are going to use the gh_users data to ask three questions:

Which user joined GitHub first?
Are all the repositories user-owned, rather than organization-owned?
Which user has the most public repositories?

In this exercise, your map_*() knowledge is really tested, so make sure to reflect on all the different flavors of map_*() and how they should be used.

1
Name gh_users with the "name" element and sort the "created_at" element to determine who joined GitHub first.
2
Output a vector that returns TRUE for each element where the "type" is "USER".
3
Output a named numeric vector of the number of "public_repos".
