Use Trie Tree to store words, and on every node place a counter, increase the counter when any word ends there.

then go for DFS search for any node which has non zero value of counter and print the path from root node to current node.

In any case you are going through all the words.. So a hashset with key as word and value as count will do the job .

How about using a map, the key would be the word & the value shall indicate the number of repetition.

This was my answer can we do better?
