-Output the full text of this proverbial rhyme:
+Given a list of inputs, generate the relevant proverb. For example, given the list `["nail", "shoe", "horse", "rider", "message", "battle", "kingdom"]`, you will output the full text of this proverbial rhyme:
```text
For want of a nail the shoe was lost.
@@ -11,8 +11,11 @@ For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.
-And all for the want of a horseshoe nail.
+And all for the want of a nail.
```

+Note that the list of inputs may vary; your solution should be able to handle lists of arbitrary length and content. No line of the output text should be a static, unchanging string; all should vary according to the input given.
