The previous section is finished. ll (1) The main framework of the analysis algorithm, now let's look at the conflict processing ... There are many ways of dealing with conflicts, and this is called eliminating left recursion ...The upper right grammar is left recursive grammar, you will find that any left recursive grammar is not ll (1), why? For example, if you look at the No. 0 and 1th of the grammar, they can be written in the following way:E = t + t + t + ...E = TIt is not difficult to find

An abstract syntax tree is generated, followed by semantic analysis ... The tasks of semantic analysis are as follows:A relatively simple type checking algorithm can be this:This can be followed by an ID:This leads to the concept of the symbol table:At the same time the symbol table should also meet the concept of scope in the program, the implementation of the scope of the method is as follows:At the same time the symbol table should also solve the problem of namespaces, you can see that the li

　　Preface In recent weeks, I spent some time learning the machine learning course of the Dragon Star program for the next summer vacation. For more information, see the appendix. This course chooses to talk about the basic model in ml. It also introduces popular and new algorithms in recent years. In addition, it also combines ml theory with actual problems, for example, it is applied to visual and Web applications. In short, although the course conte

The Dragon Boat Festival is very depressing. Originally, the weather in Nanjing was so uncomfortable that it was so cool and hot. But there are a lot of things. The busiest project is nothing more than self-closed development two days ago due to a delay in the progress of some trivial matters. As of last night, the first version of the main program had finally come out. Although the execution was not correct, I was very satisfied as long as no erro

I lowered the windows a little bit, and the cool blew the sound of the wheel rolling the ground into the car. There was a sound that Ning and Rong were familiar with. It seemed that I had never left Toshiba when I worked overtime and took a taxi home.This is the second day of the Dragon Boat Festival. I have an appointment with my former colleagues to visit the World Expo. Ning said there were about seven or eight people in total, but no one asked me,
