Course Introduction：Two ways to find files in Linux are to use the find and locate commands. 1. The find command is suitable for real-time search, and the syntax is find[path]-name "file name", which supports wildcard characters, ignoring case (-name), excluding directories (-not-path), and qualified types (-typef). 2. The locate command depends on the database faster, and the syntax is locate-b "* file name", but you need to run updatedb first to update the database. The choice of both depends on whether real-time and speed requirements are required.

Course Introduction：In C, it is recommended to use find instead of count to determine whether the std::map key exists; 2. Find has higher performance and can directly obtain values to avoid repeated searches; 3. Count is only used to judge existence, but it is impossible to obtain values; 4. Count and operator[] should be avoided in combination to prevent secondary searches; 5. Only find or count can be used for constmap, and operator[] is not available; 6. Overall, find is preferred, taking into account efficiency and function, find is a better solution.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
