Article Introduction：This article mainly introduces the binary search (halve search) algorithm of ordered table search in PHP. It briefly introduces the concept and principle of the binary search method and analyzes the related operations of ordered linear table search in PHP based on the binary search algorithm in the form of examples. Tips, friends in need can refer to it, I hope it can help everyone.

Article Introduction：Below, the Java introductory tutorial column will introduce you to the method of implementing binary search. I hope it can help you. Binary search is a binary search, which searches for specified elements in an ordered sequence and sets the minimum index, maximum index, and intermediate value.

Article Introduction：Today we will talk about "binary search". The idea of ​​binary search is to compare the size with the middle number of a certain array in a sequential array each time. The disadvantage of binary search is that the array must be sequential (I take the data sorted from small to large as an example). The advantage is that the query efficiency is extremely high and the time complexity is log2n. The more this search method is used in big data, the more obvious the effect will be. The source code and unit test are attached below. The source code contains two algorithms, one is loop and the other is recursive. Please refer to it:

Article Introduction：Binary search is also called binary search, which is a more efficient search method. However, binary search requires that the linear table must adopt a sequential storage structure, and the elements in the table must be arranged in order by keywords.

Article Introduction：How to use Java to implement binary search algorithm Binary search algorithm is an efficient search method suitable for sorted arrays. Its basic idea is to continuously narrow the search range, compare the search value with the elements in the middle of the array, and decide whether to continue searching the left half or the right half based on the comparison result until the target element is found or the search range is reduced to empty. Below we will introduce in detail how to implement the binary search algorithm in Java. Step 1: Implement the binary search method publicclassBinarySearch

Article Introduction：Binary search, also known as half search, has the advantages of less number of comparisons, fast search speed, and good average performance; its disadvantage is that the table to be looked up is required to be an ordered table, and insertion and deletion are difficult. Therefore, the binary search method is suitable for ordered lists that do not change frequently but are searched frequently. First, assuming that the elements in the table are arranged in ascending order, compare the keyword recorded in the middle position of the table with the search keyword. If the two are equal, the search is successful; otherwise, use the middle position record to divide the table into two sub-tables, the first and last. If If the keyword recorded in the middle position is greater than the search keyword, then the previous keyword will be searched further.

Article Introduction：Binary search technique, also known as half search. Its premise is that the records in the linear table must be in key order (usually in order from small to large), and the linear table must be stored sequentially.

Article Introduction：Binary search is also called half search. The binary search algorithm requires that the data must be in order. The following is the code for implementing the binary search algorithm in PHP. 1: Recursive method $array = [1,3,6,9,13,18,19,29,38,47,51,56,58,59,60,63,65,69,70,7

Article Introduction：The internal implementation of Python's list is an array, which is a linear list. To find an element in a list, you can use the list.index() method, which has a time complexity of O(n). For large amounts of data, binary search can be used for optimization. Binary search requires that objects must be ordered. The basic principle is as follows:
