This course is a basic course for Big data engineers and cloud computing engineers , as well as a course that all computer professionals must master.Without mastering data structures and algorithms, you will find it difficult to master efficient, professional processing tools, and more difficult to handle complex large

front end with techniques such as SVG. (Another scenario I came up with was to show a file tree like Windows Explorer on the front end)I thought for a long time, did not think of a circular solution, and later found the answer on the StackOverflow:var plain2Tree = function (obj) { var key, res for(key in obj) { var parent = obj[key].parent if(parent === ‘‘) { res = obj[key] } else { obj[parent][key] = obj[key] } } return res}This code is the use of JavaScript inside the reference type, then th

. (5) Merge sort can be used to sort within, or can be used for sorting outside. When you sort outside, you usually use a multi-way merge,And by solving the merging of Changshun string, the long initial string is generated, and the parallel capability of the host and peripherals is improved to reduce the number of accesses external memory and improve the efficiency of the external sequencing.2, the search algorithm can be proficient in writing or the computer code out two points to find the prog

The PHP interview questions compiled in this article mainly come from two methods: one is the string and file operation example, and the other is the examples of several commonly used sorting algorithms. Let's take a look at them. The PHP interview questions compiled in this

elements u, and another set R with R relationships. if (b) belongs to r, then elements a and B are equivalent. Equivalence classes refer to the largest set of mutually equivalent elements. In other words, the set U is divided according to the relationship, the elements within the class are equivalent and can be regarded as a kind of clustering.Offline equivalence classes: Known N and R, determine all equivalence classes.Online equivalence class: There are n elements at the beginning, and each e

traversal sequence is dabec, the middle-order traversal sequence is debac, and its pre-order traversal sequence is (cedba)18. If abdegcfh and dbgeachf are known as the forward and central traversal of a binary tree, the backward traversal of the binary tree is (dgebhfca)19. If the sequential traversal access order of a binary tree is abdgcefh and the sequential traversal access order is dgbaechf, then the node access order of the sequential traversal is (gdbehfca)20. database protection include

Linked List of data structures and algorithms Classification of linked lists: (1) single-chain table Header insertion: you only need to maintain one header node, which is often used to simulate the stack; Tail insertion: You need to maintain the head and end nodes, which are often used to simulate queues. (2) Two-way linked list Bidirectional traversal can be use
