[Algorithms] Refactor a Linear Search into a Binary Search with JavaScript

Binary search is an algorithm that accepts a sorted list and returns a search element from the list. It provides a dramatic performance boost over searching linearly through a list for an element. Let’s play around number of iterations required for e…

有序线性搜索（Sorted/Ordered Linear Search）

如果数组元素已经排过序(升序),那我们搜索某个元素就不必遍历整个数组了.在下面给出的算法代码中,到任何一点,假设当前的arr[i]值大于搜索的值data,就可以停止搜索了. #include<stdio.h> // a function to search "data" in an array "arr" of size "size" // returns 1 if the element is present else 0 int…

无序线性搜索（Unordered Linear Search）

假定有一个元素顺序情况不明的数组.这种情况如果我们要搜索一个元素就要遍历整个数组,才能知道这个元素是否在数组中. 这种方法要检查整个数组,核对每个元素.下面是算法实现: #include<stdio.h> // a function to search "data" in an array "arr" of size "size" // returns 1 if the element is present else 0 int un…

Search I You are given a sequence of n integers S and a sequence of different q integers T. Write a program which outputs C, the number of integers in T which are also in the set S. Input In the first line n is given. In the second line, n integers a…

LeetCode编程训练 - 折半查找(Binary Search)

Binary Search基础应用于已排序的数据查找其中特定值,是折半查找最常的应用场景.相比线性查找(Linear Search),其时间复杂度减少到O(lgn).算法基本框架如下: //704. Binary Search int search(vector<int>& nums, int target) { //nums为已排序数组 ,j=nums.size()-; while(i<=j){ ; if(nums[mid]==target) return mid; ; ;…

【LeetCode】35. Search Insert Position (2 solutions)

Search Insert Position Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You may assume no duplicates in the array. Here are few examples.[1,3,5,…
