Given a character x and a state k, we can get the next state by considering the string “pat [0..k-1]x” which is basically concatenation of pattern characters pat [0], pat 1 … pat [k-1] and the character x.

WebBut there is the Knuth-Morris-Pratt algorithm, which finds all substrings in O(N) complexity. Edit: Also, there is another algorithm: the so-called "Z-function" with O(N) complexity, but I couldn't find an English source for this algorithm (maybe because there is also another more famous one with same name - the Z-function of Rieman), so I will ... WebMany 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.
