Fast Forward Commit

Here's a diagram of a fast-forward merge. Before:

      C     other_branch
     /
A - B       main

After git merge other_branch:

            other_branch
A - B - C   main

No merge commit is created.

Assignment

Switch back to the main branch.
Make sure it doesn't have that last G commit with a quick git log.
Merge the update_titles branch into main. You should see a fast-forward merge happen automatically because main doesn't have any commits that aren't already in update_titles.
Delete the update_titles branch.

Run and submit the CLI tests.
