attributes defined in the DFA's state are also used by the DFA and Index to facilitate state use.
Second, NFA conversion to DFA
2.1 Subset Construction method
The NFA is converted to a DFA, and a subset construction (subset construction) algorithm is used. The process of the algorithm is similar to the NFA matching process mentioned in section 3.1 of the C # lexical Analyzer (iii) regular expression. In the NFA matching process, use is a state of

Calculator is a lot of programming beginners have done, starting from the simplest console program, input values, input operators, and then enter a value, to get a result. The interface is basically modeled on the Windows operating system calculator, through the button input values and operators, and then give the results of the operation. Can you directly enter an expression, or you can calculate several expressions, or select a part of an expression to calculate, if the input error can indicat

Today, we will introduce how to perform one-step debugging through the debugging function of the query analyzer. This is also a very practical technique. Q: How can I perform one-step debugging through the debugging function of the query analyzer? A: The specific steps are as follows: 1. Set the server [authentication] attribute to [hybrid mode] (window and SQL identity)
Today, we will introduce how to perf

The smaller the bandwidth, the more spectral resolution. However, there is a trade-off between what quickly the display can update the full frequency span under consideration and T He frequency resolution, which is relevant for distinguishing frequen

OverviewLexical analysis is the first step in the compilation phase. The task at this stage is to read the source program from left to right, one character at a time, to scan the character stream that makes up the source program and then recognize the word (also called the word symbol or symbol) according to the word-building rules. The lexical Analysis program implements this task. Lexical analysis programs can be generated automatically using tools such as Lex. This project implements a simple
