Some of the books on algorithms are very rigorous, but not comprehensive, others involve a lot of subject matter, but lack rigor.

these semantic actions at the right time, usually during the token stream of the input derived from the generated formula.According to Wikipedia's introduction to syntax-directed translation, the SDD is easiest to implement when using the Bottom-up parsing method and the SDD using the s-attributed grammar. In this case, a grammar-guided translation plan can be constructed by embedding the semantic action at the far right of the production body, which

information, Excel table or Notepad information automatically imported into this site, you can batch generate two-dimensional code business cards, these two-dimensional code card can be long-term retention.In fact, the above is not the focus, the focus is that the novice can take this project familiar with the development of two-dimensional code, familiar with the use of web framework, this is only a good example.----------------------------------------------------------------------------------

(1) After importing the Abaddressbook library, and then adding the header file, you can use it.-Because this library method is basically the C language style, so the class is basically a CF beginning, such as Cfstringref and Cfarrayref, it and OC NSString and Nsarray similar, can be converted to each other, using __bridge to cast, such as (__ Bridge NSString *) XXX, you can convert the original cfstringref xxx to nsstring type, the advantage is that there is no need to release operations in many
