  * 208. Implement Trie (Prefix Tree)
  *
  * Implement a trie with insert, search, and startsWith methods.
-
- Note:
- You may assume that all inputs are consist of lowercase letters a-z.
+ *
+ * Example:
+ *
+ * Trie trie = new Trie();
+ *
+ * trie.insert("apple");
+ * trie.search("apple");   // returns true
+ * trie.search("app");     // returns false
+ * trie.startsWith("app"); // returns true
+ * trie.insert("app");
+ * trie.search("app");     // returns true
+ * Note:
+ *
+ * You may assume that all inputs are consist of lowercase letters a-z.
+ * All inputs are guaranteed to be non-empty strings.
