Introduction to Regular Expressions:
?? Regular expressions are a grammatical rule that describes the pattern of character arrangement and matching. It is used primarily for pattern segmentation, matching, finding, and substitution of strings. So far, the exact (text) match we used earlier is also a regular expression.?? In PHP, a regular expression is generally a procedural description of a text pattern that is composed of regular characters and some special characters (similar to a wildcard c

It is a letter sequence (such as foo), or a table (list) composed of zero or multiple expressions. Expressions are separated by commas, put in a pair of brackets. the following are some expressions:(Note: The expressions in the original Lisp syntax are se

Overview
It indicates that Erlang is a dynamic language and variables are dynamically bound at runtime, which is difficult for us to obtain the type information of function parameters and returned values. In Erlang, we can use type and spec to define the data type and function prototype. Through this information, we conduct static checks on functions and calls to find some problems in code. At the same time, this information is also easy for others to understand function interfaces and can be us
different from the version controlled by userland software. Of course, userland software is reluctant to see the fact that RSS 1.0 seems to replace its version 0.94, so a new version is released and the version is jumped to 2.0.
This is today's situation, forming two major competing versions: one based on RDF 1.0, and the other based on not (2.0), but both of them share the same name. This is a terrible mess, because the version numbers lead to people mistakenly think that 2.0 is an improved ve

This time, we will continue to talk about Erlang data item memory related issues.In the Erlang efficiency_guide documentation, the memory consumption of the different data types in the Erlang system is clearly stated, in this simple one or two:
