This paper summarizes the commonly used brushes used to STL containers and some standard algorithms, including:
string、vector、map、pair、unordered_map、set、queue、priority_queue、stack，And the common operations of these containers, such as insertion, deletion, lookup, access (iterator or subscript, C++ 11 keyword auto understand? Sequential access to or random access), initialization, etc. Finally, we introduce several common functions of header files <, algorithm> and below.In particular, sort.

The original webui automation tests were run in chrome headless mode in a Linux environment, but downloading the relevant case is currently not well supported (see bug: https://bug)S.chromium.org/p/chromium/issues/detail?Id=696481), so choose to run the download-related case in non-headless mode, using the xvfb tool.
When you install xvfb and start it, you need to add the following when manually adjusting the code.
1. When setting up xvfb, set screen size: nohup /usr/bin/Xvfb: 7 -ac -screen 0 1280x900x8 &
2. Set temporary environment variables: export DISPLAY=: 7
3. Add chrome optio...
