The DFA (deterministic finite automata), a deterministic finite automaton, refers to a unique next state for each state that is determined by the input alphabet, and the NFA (Nondeterminisic finite Automata) is an indeterminate finite automaton, which means that for any state, when the state obtains the input alphabet, it is possible that the resulting state is not one, but multiple, that is, a set of state
information Interchange), issued by the National Standards Institute (American Nation Standards Institute). The ASCII character code shown in Figure 2-1 is similar to the format in an ANSI file.ASCII has many advantages. For example, the 26-letter code is sequential (not in the EBCDIC code); uppercase and lowercase letters can be transformed from one data to another, and 10 numbers of code can be conveniently obtained from the value itself (in the Bcdic code, the character "0" is encoded behind

The following I will give you a thin road.

Some people will ask the formula is not abc=de, how is there any difference?
In the professional book we often see Figure 2, the same letter because the font is different and represent
provide a good implementation alphabetindexer, it is enough to implement the contact grouping function.
The Alphabetindexer constructor needs to pass in three arguments, the first argument is cursor, the second is the Sortedcolumnindex integer, and the third argument is the alphabet string. Where cursor is to pass the cursor that we have detected from the database, Sortedcolumnindex is to indicate which column we are using to sort, and

position of the text string, the pattern string is compared to the next position of the text string when the pair fails, until the alignment succeeds.The code for this algorithm is implemented as follows:Analysis of Complexity:
In the best case, the first round is successful and the complexity is O (m).
In the worst case, the complexity is O (m* (n-m+1)), and it can be treated as O (n*m) because of N>>m, until the last pair is compared to the last character of the pattern string.Th
