Copy the code below to grocery.go and list.html files, both saved in the same directory. Then fill in the missing code in both files.
When a browser visits http://localhost:8080/fruit, your app should respond with this HTML (the spacing doesn’t have to match):
<html>
<ul>
<li>apples</li>
<li>oranges</li>
<li>pears</li>
</ul>
</html>
And when a browser visits http://localhost:8080/meat, your app should respond with this HTML:

<li>chicken</li>
<li>beef</li>
<li>lamb</li>
</ul>
