I use trie policy data structure but it is tle since distance operator is O(n) ... any help how to implement using it or it is not possible?

I am surprised this is getting so many downvotes, perhaps the question isn't very clear and seems confusing for people not familiar with the policy based structures.

Overloading std::distance does the trick. See http://codeforces.com/blog/entry/10355?#comment-163713
