Your job is to create a Git history that looks like this:

* G
* I
*   T
|\  
| * I
* | N
|/  
* I
* T
* -

Use git branch, git merge and git checkout to create the necessary commits to recreate the graph. You can check your work by running ./check.

Hints:

• The letters are commit messages- you can make a commit without changing any files by running git commit --allow-empty -m "T"
• The order you make the commits in matters; work from the bottom to top. The first commit (-) has already been made, so your first commit should be T.
• The branch names you choose don't matter
• You can checkout a commit without resetting HEAD to eg. make a branch from it, but you'll need to use git checkout main to get back to your main thread.
• Merging makes its own commits; the top T is a merge commit, there's no need to make a separate one
• If you make a mistake, use git reset --hard to return to an earlier commit. You can run ./reset to restart the entire exercise.
• ./check might not show your branch until it diverges from main
• You can see a an example solution in ./solve if you need more help

Try some more advanced graphs with check 2 and check 3!

* G
*   I
|\  
| * T
* | B
|/  
*   R
|\  
| * A
| * N
* | C
|/  
* H
* -

*   G
|\  
| * I
* |   T
|\ \  
| * | C
| * | H
* | | E
| |/  
|/|   
* | C
* | K
|/  
*   O
|\  
| * U
* | T
|/  
* B
* -

These also work with solve 2 and solve 3. This might take a lot of trial and error, good luck!
