a very common use case for regexes is to find matches that are preceded or followed by some context. a classical example being all lines that end with ‘a’. this requirement is usually expressed with a lookahead, where upon finding an ‘a’, you look ahead to check if it’s the end of the line. in a backtracking engine, this is very easy to implement - you just duct-tape the logic that checks the next character, but in a DFA-based engine, this is impossible because you cannot report “the match is here” if the next character is not even known yet. and by the time you know the next character, the position information is lost, so you can’t report the match retroactively (well, unless the distance is fixed of course..).，详情可参考搜狗输入法
Stephen Graham and Andrea Riseborough make an odd couple forged in hell. Graham is a fantastic bit of casting, as the English actor has played an array of tough guys in productions like Gangs of New York, This Is England, Public Enemies, and A Thousand Blows. More recently, however, he wowed critics and audiences by playing the heartbroken and volatile father in Netflix's harrowing crime mini-series Adolescence. Now, in Heel, Graham is doggedly gentle — until he's not.
