Approach 1. Count frequency of words in one pass. Store them in a hashmap. In the second pass find out the longest unique word using the hashmap. Assuming constant time map operations, complexity is O( |S| ), where |S| is the sum of the word lengths.

Approach 2. Can be done using a suffix trie. Order O( |S| ).
