A data structure is a collection of one or more specific relationships that exist between each other.The popular point is the logical structure of the data, such as what kind of structure the data is stored in memory.General data structures: arrays, linked lists, trees, hash

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

From coolshell (from a website: data structure visualizations) Do you still remember the previous article about visual sorting? On the Internet, I saw a home page for various visual data structures and basic algorithms by David galles from the University of San Francisco. The website is here for you to see. I listed t

structure of linear tables, where the time complexity is O (1), regardless of the location of the data being stored or read. When inserting or deleting, the time complexity is O (n), indicating that it is more suitable for the number of elements stable, not often inserting and deleting elements.Advantages:① no need to add additional storage space to represent the logical relationship between elements in a table② can quickly access elements from anywh

, so the time complexity of the algorithm T (n) =0 (degree (v)). ⑵updatesize (): Also if the child of node v changes, the current node should be updated and the size of its ancestors. Because the scale of any node in the binary tree is equal to the size of its left and right sub-tree and the node itself, and the size of the subtree only need to get the node around the size of the child can be obtained, only the θ (1) time. Thus the algorithm's time complexity T (n) =0 (level (v)). ⑶sever (): Cut
