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。
Write a JavaScript function that performs recursive binary search and returns the index of the found element. Write a JavaScript function that applies binary search on a sorted array of objects based on a specified key. Write a JavaScript function that implements binary search and returns the index...
代码如下: varsearch =function(nums, target) {varl=0,r=nums.length-1;while(l<=r){varmid=parseInt((l+r)/2);if(target===nums[mid])returnmid;elseif(target<nums[mid]) r=mid-1;elseif(target>nums[mid]) l=mid+1; }return-1; };...

二分查找也称折半查找(Binary Search),它是一种效率较高的查找方法。 ☃️使用条件: 必须是一个有序的序列。 例如:在1,2,3,5,7,9,10,15,18中,查找到10这个数字,它是一个有序的数列,因此可以使用二分查找! 🤔📝算法思维: 二分查找又称折半查找,顾名思义就是用折半的方法去找到目标数字,这让...

二叉搜索树树(Binary Search Tree),它或者是一棵空树,或者是具有下列性质的二叉树: 若它的左子树不空,则左子树上所有结点的值均小于它的根结点的值; 若它的右子树不空,则右子树上所有结点的值均大于它的根结点的值; 它的左、右子树也分别为二叉排序树。
