This code produces the following output.
The target Array contains the following before:
 The quick brown fox jumped over the lazy dog
After copying the keys, starting at index 6:
 The quick brown fox jumped over B A dog
After copying the values, starting at index 6:
 The quick brown fox jumped over valueB valueA dog
