The KMP algorithm (Knuth-Morris-Pratt algorithm) is a well-known string matching algorithm. It is very efficient, but it is a bit complicated.
Many readers complain that the KMP algorithm is incomprehensible. This is normal. When I think about the KMP algorithm explained in university textbooks, I don't know how many future Knuth, Morris, Pratt will be dismissed in advance. Some excellent students use the process of pushing the KMP algorithm to help understand the algorithm. This is a way, but this article will help the reader understand the principle of the algorithm from a logical level. Between ten lines of code, KMP died.
