Recently made a topic tree line and Fenwick tree of the knowledge of these issues and learned two weeks did was review. Feeling segment tree do not do a string faster. Segment tree sometimes need to transform thinking, clever thinking can achieve very good results. It is a good summary of the opportunity. In doing theme while still learning ac suffix automata and automata, which together control is not very good, and thought the finish line on the suffix tree automata and ac automata.
