It seems to waste time on reading the title. . .
T1 really do not see what that explanation that the sample is to engage something, and eventually found a second sample had not realized that I was wrong,
First calculate complexity to verify their understanding of right , T1 is not so simple,
T2 violence complexity of metaphysics, and he was not the end,
T3 violence ah no 20 points
T1 will not permit the examination room also permit does not come out, violence, bad play, but there are huge guys play out, lift

100opts: Obviously the complexity of the enumeration of prefixes and suffixes can be optimized,
We deal with it at some point the trie string as a prefix or suffix ending
