Collections Practice

1. sort the following array in ascending order
  ["blake", "ashley", "scott"]
2. sort the following array in descending order
  ["blake", "ashley", "scott"]
3. put the following array in reverse order
  ["blake", "ashley", "scott"]
4. grab the second element in the array
  ["blake", "ashley", "scott"]
