two two sequential sequences in one-dimensional array into an ordered sequence. The merging algorithm can also be implemented by recursive algorithm, which is simpler in form, but has poor practicability.
The number of merged algorithm merges is a very important amount, according to the calculation when there are 3 to 4 elements in the array, the number of merges
is 2 times, when there are 5 to 8 elements, the number of merges is 3, when there are 9 to 16 elements, the number of merges is 4, ac

Basic idea:The simplest sort, and also the most time-consuming sortIn the set of numbers to be sorted, the total number in the range that is not currently in sequence, the top-down pairs of adjacent two numbers are compared and adjusted sequentially, so that the larger number to sink , smaller upward. That is, each time a comparison of two adjacent numbers finds that they are in the opposite order of order, they are interchanged. Example of bubbling s
Classic Sort algorithm-bubbling sort bubble sort
The principle is that the proximity of the number 22 is compared, in order from small to large or from large to small,
After such a trip, the largest or smallest number was exchanged to the last one,
And then start from the beginning of the 22 exchange, until the end
Basic ideasIf the order is sorted from small to large, the sorted array is traversed, and if the current value is greater than the subsequent value then it is exchanged and traversed continuously until no exchange action occurs. The best time for bubbling sorting is O (n), and the worst time complexity is O (N2), so the average time complexity of the bubble sort is O (N2), and the

This article mainly introduced the PHP sorting algorithm bubble sort (Bubble sort) Implementation method, referring to the big data structure of the algorithm, combined with the case form more detailed analysis of the bubble sorting principle and related implementation skill
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];
