Why a page replacement algorithm is requiredThe operating system places only "common" data and code in the application in physical memory, while infrequently used data and code are placed on storage media such as the hard disk. If your application accesses "common" data and code, the operating system is already in memory and there is no problem. But when an application accesses data or code that it believes should be in memory, a fault is generated if

The following principle source: http://c.biancheng.net/cpp/html/2614.htmlIn the process of address mapping, if you find that the page you want to access is not in memory, a page fault is generated. When a page break occurs, if there is no free page in the operating system memory, the operating system must select one of the pages in memory to move it out of memory to make room for the page to be paged in. The rule used to choose which page to retire is called the page
In the process of address mapping, a page fault is generated if the page that you want to access is no longer in memory. When a page break occurs, the operating system must select one of the pages in memory to move it out of memory to make room for the page that is about to be paged in. The rule used to choose which page to retire is called the page replacement algorithm. The common permutation algorithms are:1) Best

Motivation
When we designProgramModule, we will create some class hierarchies, and then we will create their subclasses by extending some classes.
We must ensure that the child classes only expand without replacing the parent class, otherwise unexpected results will occur when we use them in existing program modules.
The Rys replacement principle indicates that when a program module uses a base class, the reference of the base class can be re
