"Automaton"The function of the finite state automaton is to recognize the string, and the self-motive A can recognize the string S, which is recorded as $ A (s) $=true, otherwise $ A (s) $=false.The automata consists of the $alpha$ (character set), $state $ (State collection), $init $ (initial state), $end $ (End-state collection), $trans $ (State transfer function).The $trans (S,STR) $ indicates that the current state is $s$ and is read into a string or character after $str$ the state is reache

According to Luo's thesis, an ascii code must be added to the middle of the two strings, which is a character smaller than any letter. Longest public substring (pku2774, ural1517)Returns the longest common substring of two strings A and B.Algorithm analysis:Any substring of a string is the prefix of A suffix of the string. The longest common substring of A and B is equivalent to the maximum value of the longest common prefix of A and B. If you enumera

The suffix array has always been very powerful, and its statistical function is one aspect. The following uses two examples to illustrate how to use a powerful suffix array for statistics. [Example 1] poj 3415 http://poj.org/problem? Id = 3415 This is the number of substrings with length> = K in the two strings (repeated) Practice: first, the most common practice is to use a

Http://blog.csdn.net/ysu108/article/details/7795479 Returns the substring that appears the most frequently in a string. For example, the string "abababc" can appear at most AB consecutively, three times in a row. To distinguish it from the longest duplicate substring in a string, or the above string, the longest duplicate substring is Abab. The solutions for the two questions are somewhat similar, and the data structure of the suffix array is used.

Label: style blog HTTP Java SP strong file Div on Problem description There are multiple file names separated by semicolons with suffixes (for example, 1.xml20.2.20.3.jpg00004.txt). You can write a C program to find the first file name that meets the suffix requirements and display the file type. The specified suffixes and file types correspond to the following: Voice: Type 1, suffix WAV; Video: T

The main topic: give you a string, give you a query n times, each time you give you an interval to find out how many substrings in this interval.Problem-solving ideas: We must enumerate the position, then find the common substring and then remove the duplicate, but his address corresponding to rank is not continuous, if the violence to find the words will n*n time out.From this blog to learn a method: first to the entire string sa[] and height[], then for any interval [L, R], traverse through sa
