relatively short, so the rollback to 0 does not have a very large impact, however, the I rollback range is also very large, and the comparison result in the middle of the round is changed to 0,The KMP algorithm is an algorithm that enables I not to roll back, and J to roll back a part (in the worst case, all. How can we achieve this? For example:S = gggabcabcP = abcacS3s4s5s6 = p1p2p3p4 = ABCA, but S7! = P5: for general algorithms, the pointer I of S

If eventlistener2 calls the stoppropatation () of [S5], eventlistener3 continues to run. However, if eventlistener2 calls stopimmediatepropagation (), eventlistener3 will not proceed. 10. removeeventlistener () can only remove one listener at a time. When several listeners are added to the same event, remove
