Notes:
① The coordinates of the rectangular vertices must be re-sorted and used again. It is only a reference for discuss to say that the top is not strictly above the top, so we need to re-sort and re-use them in the lower order.
② Because the inside of the rectangle is also part of the rectangle, the line segment is considered to be at the intersection of the rectangle in the rectangle.
③ When determining whether the four sides of a line segment and a rectangle have intersecti
When making reports such as resumes, we usually need to display images in the reports. If we do not use "detailsection", we must insert a subreport to display images.
Create the data source file of the subreport:

Endpoint reference
A Web service endpoint is a referenced entity, processor, or resource that can be used as a Web Service Message target. An endpoint reference conveys the information required to identify or reference a web service endpoint, it can be used in a variety of ways: the endpoint reference can be used to convey the information required to access the Web service endpoint, or to provide addresses for each message between Web Services. See the
10.2.1 to avoid stack overflow with tail recursion (cont.)[Na?veIt's not like English, I don't know what it means.]The list-handling function in the sixth chapter is not tail-recursive. If we pass a large list, it will fail because of the stack overflow. We will rewrite the two functions (map and filter) with tail recursion to correct this problem. For comparison purposes, the original implementation is included in listing 10.8. To avoid name collisions, it has been renamed MAPN and Filtern.List

3. For the sort () and sorted () functions, the incoming parameter key is more efficient than the parametric CMP. The function that the CMP passes in is called multiple times throughout the ordering process, and the key is processed only once for each element.

The purpose of setting unused is to use the unused flag to delete the unused when the cpu, memory, and other resources are insufficient.
After setting the unused column, the column data is not deleted immediately, but hidden physically. The recovery steps are as follows: back up a data dictionary before testing.
