substring searching algorithm search ^ 3. 结果第一个字符就不匹配,再看文本串中参加匹配的最末位字符的下一位字符,是'r',它出现在模式串中的倒数第3位,于是把模式串向右移动3位(r 到模式串末尾的距离 + 1 = 2 + 1 =3),使两个'r'对齐,如下: substring searching algorithm search ^ 4. 匹配成功。
Another example: Next = short string = 0+1 0+1 1+1 1+1 2+1 3+1 KMP Algorithm : In long string: KMP don’t need to reset the index in long str ,when an iteration ends. It can keep going and never go back. In short string: which index KMP will select depends on Next table...
The idea of the KMP algorithm needs to be understood on the basis of violent matching, mainly focusing on the mismatch during the matching process. We assume that there is a text stringText_strand a matching stringPat_str. When usingPat_strto match a text string, Assuming that the part we...
Take a look at the complete construction process of the state transition diagram, you can understand the subtlety of the role of the state X: At this point, the core of the KMP algorithm has finally been written. Take a look at the complete code of the KMP algorithm: publ...

for example, be input to a signature algorithm which generates or verifies the signature for the message. Signing the message digest rather than the message often improves the efficiency of the process because the message digest is usually much smaller in size than the ...
