What are the specific changes?

To identify specific changes in a file like hello.txt, you can use Git to view the commit history. Here’s how you can check the changes made in the first and second commits:

View Commit History:
```
git log
```
This will show you a list of commits with their messages and hashes.
View Changes for Specific Commits:
To see the changes made in the first commit, use:
```
git show <first-commit-hash>
```
For the second commit, use:
```
git show <second-commit-hash>
```
Combine Changes:
If you want to combine the changes from both commits into your working directory, you can use:
```
git cherry-pick <first-commit-hash>
git cherry-pick <second-commit-hash>
```

This will apply the changes from both commits to your current branch. If you need further assistance or specific details about the changes, please provide more context!
