Implementation of linked list (complete code attached at the end of the article)
The concept and structure of linked lists A linked list is a non-continuous and non-sequential storage structure in terms of physical storage structure. The logical order of data elements is realized through the pointer link order in the linked list The sequence table we learned in the previous article is stored continuously For example: The […]
Implementation of Spring-SpringAOP
Understanding of Spring AOP OOP stands for object-oriented programming, which is a programming idea, and AOP stands for aspect-oriented programming, which is also a programming idea. Spring AOP: Technical support provided by Spring to make it easier for programmers to implement aspect-oriented programming. A set of mechanisms provided by Spring make it easier for us […]

Lab8: Locks | Lock optimization implementation
Lab: locks Memory allocator (moderate) Your job is to implement per-CPU freelists, and stealing when a CPU’s free list is empty. You must give all of your locks names that start with “kmem”. That is, you should call initlock for each of your locks, and pass a name that starts with “kmem”. Run kalloctest to […]
Implementation code of AES/ECB/PKCS5Padding algorithm for secret key encryption and decryption of any length consistent with JAVA, Python and PHP
Recently, I encountered an AES encryption algorithm that needs to be implemented in Java, Python, and PHP. In fact, it is not very complicated in nature, but the parameter adjustment is quite troublesome. I found some reference materials and finally got it. The actual code is as follows: Main features The three languages of JAVA, […]
