Search Results for "perfect binary tree"

A really fast static spatial index for 2D points and rectangles in JavaScript. An efficient implementation of the packed Hilbert R-tree algorithm. Enables fast spatial queries on a very large number of objects (e.g. millions), which is very useful in maps, data visualizations and computational geometry algorithms.

Perfect system authority management, the system can customize roles and grant different permissions for different roles. Integrated unified login, the system supports user authentication through external systems.

A complete fully tested and documented data structure library written in pure JavaScript. Buckets also includes several functions for manipulating arrays. A bag is a special kind of set in which members are allowed to appear more than once. Binary search trees keep their elements in sorted order, so that lookup and other operations can use the principle of binary search. Dictionaries map keys to values, each key can map to at most one value. A heap is a binary tree that maintains the heap property. Every node is less than or equal to each of its children. A linked list is a sequence of items arranged one after another. ...

...The read-write head itself is a state engine, which is affected by the input from the track, and which decides what to write on the track, and where to read the next input, by "moving" the head back or forth. In 5050, the part of the track left of the head is represented not by a line or stack of information, but by a binary tree. The part right of the head is represented by a binary tree, too. The head itself sort of sits between the two trees, but will often change its state according to information from the right side of the left side. In 5050, the state of the head itself is again represented as a tree of commands, although for simple programs, a linear representation can be sufficient.
