二分搜索(Binary Search) 文承上篇,搜索算法中除了深度优先搜索(DFS)和广度优先搜索(BFS),二分搜索(Binary Search)也是最基础搜索算法之一。 二分搜索也被称为折半搜索(Half-interval Search)也有说法为对数搜索算法(Logarithmic Search),用于在已排序的数据集中查找特定元素。
js 二分查找(Binary Search) 数组二分查找: 1.先对数组排序,从小到大排序 2.定义两个指针,左指针(left)指向数组第一个元素,右指针(right)指向数组最后一个元素 3.取数组中间(nums[mid])的项和目标值(target)比较 4.如果中值小于目标值,说明目标值在后半数组,将左指针(left)指向nums[mid+1],若大于同理...

This is a really tiny, stupid, simple binary search library for Node.JS. We wrote it because existing solutions were bloated and incorrect.This version is a straight port of the Java version mentioned by Joshua Bloch in his article, Nearly All Binary Searches and Merge Sorts are Broken.Thanks...

The goal is to create the fastest and at the same time the simplest JS balanced binary search tree library. Example usage of trees: // create a tree using a custom compare function var tree = bbtree(function (a, b) { return a - b; }); // insert items tree.insert(1, 'foo'); ...

A binary search tree is balanced if and only if the depth of the two subtrees of every node never differ by more than 1. If there is more than one answer, return any of them. Example 1: Input: root = [1,null,2,null,3,null,4,null,null] Output: ...
Given the root node of a binary search tree (BST) and a value. You need to find the node in the BST that the node's value equals the given value. Return the subtree rooted with that node. If such node doesn't exist, you should return NULL. ...
