flip a: null B: 41 c: 23 Third time: B-> c a: null B: 1 C: 423 B flip a: null B: 1 C: 423 Fourth time: B-> c a: null B: NULL C: 1423 Idea: This question can be done with a two-way linked list, because a and B both have a flip operation, while a two-way linked list can traverse the elements of a table in two directions, so after the flip, it is equivalent to taking the linked list element from another direction. In the end, two-way linked lists are used to represent a and B, and a stack is used

I have read 10 books to summarize them. However, this book on career planning should be shared in advance.

People who want to seriously study UNIX environment advanced programming may want to knock the example in the book and run a look at the effect. But for the novice, there may be some difficulty, because the example used in the header file and some functions do not know where, the compilation may also be problematic.

the number of objects, and all objects share such a domain or method. Instead of a static field, you have one storage space for each object. When declaring a thing to be static, it means that the field or method is not associated with any object instance of the class that contains him. that is, the properties and methods declared with static belong to the class itself, not to the object . This static method can also be called when an object is not created. Because you do not need to creat

There is no source code glpushattrib (gl_line_stipple) Glpopattrib (). So there's going to be a final draw. The information that is provided in the drawing is redrawn each time the updated dash time is overwritten before the line has been developed.
