§ 5 frame and coordinates
ICartesian coordinates of spatial points:
The Cartesian coordinate system of the plane establishes a one-to-one correspondence between points on the plane and a pair of Ordered arrays, and communicates the research on the plane graphics and numbers.
In order to communicate the research of spatial graphics and numbers, we use a method similar to the plane analytic ry, which is achieved by introducing the spatial Cartesian coordinate system.

In the process of daily project development and implementation, there will be a series of problems and tasks around the system, such as requirements, defects, suggestions, and tasks. In the context of systematic development of work information, generally, a unified problem tracking platform is used to record, track, and manage various problems, such as Jira and ITSM. The appendix summarizes and standardizes the problems I encountered during the early promotion and use of the problem tracking pla

If the number is equal to 5, it indicates that it cannot be put. 0 is returned, and each heap of candy has a maximum quantity. The result is also to be completed. Note these boundary conditions. A new knowledge is found here: when using memcpy, if not all data in it is required, specify the length. Otherwise, an error may occur.
