radixTrie satisfies Trie interface.
Trie.Add and Trie.Get don't return errors. Trie.Get should return a boolean value instead of error.
Typo: Replace "tire" " with "trie".
Write tests to verify the correctness of radixTree.Add and radixTree.Get.
Replace "Trie.Add" with "Trie.Update" because it can replace an existing value with new value.
Keys, which are not contained in a trie, are mapped to nil values.
Test should show the message to explain why an error occured.
Import an implementation of radix tree from my project.
Test should show the message to explain why an error occured.
Iterator has only Next().
