Here you can see some key words: linked list( Ordered linked list), index, binary search. It has the same performance as red black tree and AVL tree, but the principle of table hopping is very simple and its implementation is much simpler than red black tree. Skip table can not only improve the search performance, but also improve the performance of insert and delete operations. Jump table adds multi-level index to the original ordered linked list to realize fast search through index. Skip list is a randomized data structure, which is essentially an ordered linked list that can perform binary search. Skip list (full name: skip list) is a data structure used for fast search and search of ordered element sequence. The jump table (abbreviated as jump table) was developed by American computer scientists William Pugh was invented in 1989。 In his paper skip lists: a probabilistic alternative to balanced trees, he introduced in detail the data structure, insertion and deletion of jump tables. Understanding the jump table is really enough. This paper introduces the jump table in the front, and the later part introduces the design and implementation of the jump table in detail.

It may take a long time to really write it, and it may also take a lot of data to consult.

Because the core principle of many data structures and algorithms may be simple, but to understand their execution process, you need to use your brain to think about it, but if you can write it out, you have to design and implement it step by step. Don’t be afraid to meet an interviewer like mushroom head, because you don’t have to be embarrassed like a panda when you see this article.įor a data structure or algorithm, the number of people tends to shake down from hearing the name, understanding the basic principle, knowing the execution process and being able to write by hand. This is no, let’s restore a scene for everyone:īut don’t panic. In addition, you may be asked in many scenes of the interview, and occasionally you will be asked to write by hand (skipping the table may make handwriting, but red and black trees are impossible). It has been applied in many middleware and languages. Jump table is a data structure often asked in interviews. Lua table is unique powerful stuff.The article has been included in My GitHub bigsai algorithm preface The constructor is an expression to create and initialize the table. For example string.format indication "format" to index the table string. Lua also through the table to resolve the module (module), the package (package) and the object (Object) of. Lua table size is not fixed, you can expand according to their needs. Lua table with the associated array, you can use any type of value to make an index of the array, but this value is not nil. Lua table is a data structure used to help us to create different types of data, such as: digital, dictionaries.
