Algorithm analysis and improvement of bubble sort
The basic idea of exchange sorting is: 22 Compare the keywords of the records to be sorted, and find that the order of the two records is reversed to exchange until there is no reverse-order record.The main sorting methods for applying the basic idea of exchange sorting are bubble
for the bubble sort is . Algorithm stabilityThe bubble sort is to move the small element forward or the large element back. The comparison is an adjacent two element comparison, and the interchange also occurs between these two elements. So, if the two elements are equal, I think you will not be bored to exchange t
First, the principle of bubble sortBubble sort, that is, starting from the first element, through 22 exchange, so that the small first out, and then go to the second round to make the second small to come out, until the last round of the biggest out, sort of completedSecond, the bubble
Directory (?) [+] Introduction to bubble sort algorithm
The bubble sort is simpler than the insertion sort, pushing the largest element progressively to the highest bit (currently dealing with the highest bit of the child array). As I understand it,
[7]]) inner layer seventh trip: [(3rd [7]]) inner layer eighth trip: [[7] (2nd [7]]) inner layer nineth trip: [7, (+), (+), (1st) [7]]) ...In fact, the bubble sort is similar to the choice of sorting, the same number of times, is n * (n + 1)/2, but the bubble sort in the selection of the minimum value of the process w

This article brings to you the content is about the Java sorting algorithm: Bubble sorting algorithm Implementation (code), there is a certain reference value, the need for friends can refer to, I hope you have some help.
Bubble Sort method is one of the most basic sorting methods, and the mechanism of
Bubble sorting basic idea: In order to sort the number of the current is not yet ranked in the range of all the number, the top-down to the adjacent two numbers in turn to compare and adjust, 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.Borrow Hip-hop algorithm one of the p

Basic introduction
Bubble sort is the comparison of two adjacent elements, through the constant comparison, the larger number to sink, smaller to the top, which is the source of bubble sort name

First, what is bubble sort: the bubbling sort is compared between two adjacent numbers, where the previous value is defined as before, and the following value is defined as after; when Before>after I, exchange their values, if beforeThe time complexity of bubble sort is indi
The principle of bubble sorting: his basic principle is to compare the values of the adjacent elements (in particular, and the group comparison), if the conditions are met to exchange element values, the smaller elements and the larger elements of exchange, so that small elements like small bubbles from the bottom up to the top, large elements like large bubbles from the top of the sink to the end.1.
