如果遇到了字符 "C",根据箭头指示,应该转移到终止状态 5,这也就意味着匹配完成: 当然了,还可能遇到其他字符,比如 Z,但是显然应该转移到起始状态 0,因为 pat 中根本都没有字符 Z: 这里为了清晰起见,我们画状态图时就把其他字符转移到状态 0 的箭头省略,只画 pat 中出现的字符的状态转移: KMP 算法最关键的步...

做法是将模式串向右移动m个字符,即 goodSuffixShiftTable[k]=m,例如图二中case 3a,这里j=1,T[i]=a,P[j]=z,k=2,显然没有任何prefix跟bc的唯一一个proper后缀“c”完全相等,于是得出X为模式串 的下一次匹配位置。
In order to escape from such boring job, the innovative little cat works out an easy but fantastic algorithm: Step1. Connect the father’s name and the mother’s name, to a new string S. Step2. Find a proper prefix-suffix string of S (which is not only the prefix, but also the ...
