The API allows you to walk through the tree in sorted order. For that, you can retrieve the next or the previous of any inserted nodes. You can also get the first (leftmost) and the last (rightmost) node of a tree. Installation ...

二叉搜索树(Binary Search Tree,简称BST)也称为二叉查找树、有序二叉树(Ordered Binary Tree),或排序二叉树(Sorted Binary Tree)。二叉搜索树是一颗空树,或具有以下性质的二叉树: 如果任意节点的左子树不为空,则左子树上所有节点的值小于它的根节点的值。
A gas-efficient Solidity library using the iterative (rather than recursive) Red-Black binary search tree algorithm to help you maintain a sorted uint key index for your data. Insertions, deletions and searches are in O(log n) time (and ~gas). Note that the key of 0 is prohibited. Use...

a binary tree is a data structure that consists of nodes connected by edges. each node has at most two child nodes, which are referred to as the left child and the right child. binary trees are used in computer science for various purposes, including searching and sorting data. how do i...
There are some constraints which must be observed, one of which can be called a “Genealogical constraint”. For example, an input and output of the same logic function should not be swapped. Viewing a cone of logic as a family tree, a node must never be swapped with one of its ancesto...
