PHP implements bubble sorting and php bubble sorting. PHP implements bubble sorting. php bubble sorting 1. First, we must find out what is bubble sorting. without understanding the principle of bubble sorting, we cannot write code

Bubble Sort is a simple and stable sorting algorithm. Bubble Sorting Algorithm step: Compare adjacent elements. If the first element is larger than the second one, the two of them are exchanged. perform the same operation on each adjacent element, the final element is the largest. In addition to the obtained largest element, repeat the remaining elements in the previous step until no elements need to be com

Basic idea: Bubble sort is an exchange sort, and its basic idea is: 22 compare the keywords of adjacent records, if the reverse order is exchanged, until there is no reverse sequence of records. The simplest sort implementation: Let's take a look at the sort methods that are often used before you learn all sorts of sorting methods (at least I do ...). ）： This uses type hint array, unfamiliar or not accustomed to the students can be removed, do not af

1 in the mobile phone we open the fish bubble, click on the bottom of the "message", and then we find a good friend to send red envelopes (pictured below) 2 After entering, we click on "+" and then click "Red Envelope";(the following figure) 3 in this interface, we click on the amount of red envelopes, the last click "Reward" can be. (pictured below) Well, the above is a small series for you to organize an article on the Fish

The principle is that the nearest number 22 is compared in order to be exchanged from small to large or from large to small , so that after a trip , the largest or smallest number is exchanged to the last , and then start from the beginning to the 22 comparison Exchange , until the second to the bottom of the end. Example :from small to large order , bubbling Methodint[] Date = new int[] {3,5,1,6,7};int temp;for (int i=0;ifor (int j=0;jif (Date[j]>date[j+1]) {temp = Date[j];DATE[J] = date[j+1];

Copy Code code as follows: /** * Bubble Sort Bubble sort * * Principle: Multiple loops to compare, each time the maximum number of comparisons to move to the top. Each time you loop, find the maximum value in the remaining variable, and then reduce the scope of the query. This completes the ordering of this array after several loops. */ function sort_bubble ($list) { $len = count ($list); if (e

1. Compare and sort bubble sort, and sort bubble Bubble Sorting is one of the most entry-level algorithms in sorting algorithms. It is easy to understand and often serves as an entry-level Algorithm for sorting in the classroom. Bubble Sorting is known as a business. The sorting process is like a

Vernacular sorting algorithm-Bubble sorting, vernacular algorithm-bubble Preface: These two days I studied the sorting algorithm. The algorithm is abstract and easy to bypass without a stroke. So I came up with a demonstration by queuing in the physical education class. The scenario of other chapters in the series is the same as above Bubble Sorting:I repeatedly

Another PHP implementation of the Bubble sorting algorithm sharing, PHP bubble sorting algorithm The classic bubble sorting method has always been one of many programs, and the bubbling sort method is more efficient than the PHP system function sort. This chapter does not discuss performance, so do not compare it to the system capability. The

Python and Bubble sorting, python Bubble Sorting In the previous article, we introduced a very fast sorting algorithm-bucket sorting, but its disadvantage is that it consumes too much resources. The algorithm to be implemented this time does not consume too much resources, it is a bubble sort. Question: Sort the following data in ascending order: 9, 2, 8, 6, 4

Copy codeThe Code is as follows: /** * Bubble sort * * Principle: compare multiple cycles and move the maximum number to the top of each comparison. During each loop, find the maximum value in the remaining variables and then reduce the query range. After multiple loops, the array is sorted. */ Function sort_bubble ($ list) { $ Len = count ($ list ); If (empty ($ len) return $ list; For ($ I = 0; $ I {For ($ j = $ I + 1; $ j {$ Flag = '';If

The efficiency is low, the time complexity should be O (n*n) bar. Although bubbling is a relatively simple sort, it is helpful to write it again or to help you to understand and remember deeply. /*============================================================================= # # FileName:BubbleSort.cpp # Desc: Bubble Sort # # # Author:yulu # email:187373778@qq.com # # created:2014-05-01 23:51:00 # Version: 0.0.1 # History: # 0.0.1 | Yulu | 2014-05-01
