Article Introduction：In this problem, we will create a C program to simulate a nondeterministic finite automaton (NFA). NFA (Non-Deterministic Finite Automata) finite state machine can move to any combination of states of the input symbols, i.e. there is no exact state the machine will move to. The formal definition of NDFA - NFA/NDFA (non-deterministic finite automaton) can be represented by a 5-tuple (Q, Σ, δ, q0, F), where -Q is a finite set of states. Σ is a finite set of symbols called an alphabet. δ is the transition function, where d:Q×Σ→2Q (the power set of Q (2Q) is adopted here, because in the case of NDFA, the transition from one state to any combination of Q states can occur) q0 is to handle any The initial state of the input (q0∈Q). F is

Article Introduction：The efficacy and function of Ganoderma lucidum spore powder and how to consume it: The efficacy and role of Ganoderma lucidum spore powder and how to consume it Method 2 of displaying the webpage normally in any character set (continued): Transfer to: coolcode.cn I wrote an article a few days ago in any character set The method for displaying web pages normally under a character set is very simple, that is, using NCR to represent all character sets except the first 128 characters. However, I did not introduce the specific conversion method because I thought it was too simple at the time. But later I found someone asked this question, so I will explain it in detail here. The first step is to convert the string of the source character set into the UTF-16 character set. This step is because each character in the UTF-16 character set is two bytes, and it is easy to process later.
