问题 KMP is for searching,what's the one for replacing? 回答1: "Replacing" is nothing more than correct copying of the right (non-matched) substrings, while inserting the substitution for the matched pieces (which is a pretty trivial task, quite independent of algorithmic issues!-). So, if you know that KMP is the best algorithm for the searching subtask (not as cut-and-dried an issue as you present it, in the general case), it will also be best for "replacing" (especially if you "replace" by making
