所谓“撞人族”着装外表与普通行人无异，常在东京池袋、涩谷，大阪心斋桥、道顿堀等人流密集区域，针对外国游客或女性、儿童、老人等弱势群体，在擦肩而过时蓄意肘击、恶意冲撞，致他人受伤，后迅速混入人群逃走。
DFA construction is O(2^m) in the worst case, where m is the size of the NFA. this is widely known in academic circles, but in practice, most people think well of DFAs because they are used in tools like grep that are optimized for the common case. but if you throw a large regex at them, they will blow up in size and become unusable. DFA matching is linear O(n) where n is the size of the input, and the constant is ~3-4 assembly instructions per character - faster than anything you could write by hand.
