1./proc DirectoryThe Linux kernel provides a mechanism for accessing kernel internal data structures and changing kernel settings at run time through the/proc file system. The proc file system is a pseudo-file system that only exists in memory and does not occupy external memory space. It provides an interface for accessing system kernel data in a file system man

mapping of key-value pairs, the relationship belongs to the inner object in the collection, which has direct access to the elements in the collection. In practical applications I think more of the nesting of maps.The tool class (collections, Arrays) Collections Collection Tool class is an operation combined with a specialized tool class which is defined by a static method, A variety of sorting binary lookups for the list collection (analogy string op

be very low, because arraylist needs to move a large number of elements inside it. The following is an example of using arraylist: Package CLS; import Java. util. *;/*** arraylist array test * 2013.3.22 **/public class arraylisttest {public static void main (string [] ARGs) {arraylist The listlist class implements the list interface using a linked list. This means that the shortlist can be effectively added, deleted, or inserted. However, for access operations, it is not as efficient as arra

, vi belongs to V-S. Then, the shortest path is compared with the source point A to the path length of the node vi, the minimum length is the shortest path from source point A to Node VI. Finally, the end of the shortest path (i.e. VI) is added to the S(3) Repeat step (2) until the shortest path of all endpoints is found, that is, the number of nodes in S is equal to the number of nodes in V.The time complexity of the Dijkstra algorithm is O (n^2), the spatial complexity depends on the storage m

symbols table ( symbol table) This series of articles mainly introduces the commonly used algorithms and data structure knowledge, recorded is "Algorithms i/ii" the content of the course, using the "algorithm (4th edition)" This red scroll as a learning material, language is java. I needn't say much about the fame of the book. Watercress score 9.4, I also think it is an excellent learning algorithm for books. through this series of articles, you can

-set receives a tree height effect and is less efficient. Therefore, there are two kinds of improved heuristic algorithms.The first is to merge by rank, and for each node to record his height, change the father of the smaller node to the larger one. If both sides are equal, select one as the father, and the rank of the root node plus one.The second is path compression, and each time the find-set is called, the father of the node found on the path is changed directly to the root node.1make-SET (x

Data Structure practices-circular double-stranded table applications and data structure practices This article focuses on the basic series of online courses on data structures (2): practical projects of linear tables. [Project-circular double-stranded table application]The

of the relatively small redis in order to save memory will be similar to a one-dimensional array to compact storage, without the use of a real HASHMAP structure , the encoding of the corresponding value Redisobject is Zipmap, and when the number of members increases, it automatically turns into a true hashmap, at which time encoding is HT. List Common commands:lpush,rpush,lpop,rpop,lrange and so on. Application Scenarios: Redis list has a lot of

into the fourth chapter, the main point of this article is coding (that is, serialization ) and code upgrade some scenarios, to comb the memory involved in the process of encoding and decoding. The current mainstream codec is from the Apache Avro, from the Facebook Thrift and Google protocolbuf, in this article, We will also comb the advantages and pain points of various codes. 1. Non-binary encoding formatA program typically processes data in at

Tree-structure data is a solution for distributed applications based on relational databases. The question is very big. To put it simple, it is actually that tree-structure data is often used in distributed applications, such: organization structure, bill of materials, etc. However, the

Using linq2xml for data storage is a good choice for client applications. (1) The XML file is a simple database, and all data structures are defined in it. Xelement or xdocument is the intermediate amount of data conversion. (2) JSON is the storage content of each record.
