bubble sort algorithm java

Bubble Sort: is to compare adjacent two elements by index, if greater than/less than (depending on whether ascending or descending order is required), replace, or do not changeSuch a round down, comparing the n-1 times, n equals the number of elements; n-2,n-3. Until the last round, compared 1 timesSo the number of comparisons is decreasing: from n-1 to 1Then the total number of comparisons is: 1+2+3+.....

The process of bubbling sorting is to first compare the keywords of the first record with the keywords of the second record, and, in reverse order, Exchange two records and then compare the keywords for the second record and the third record. And so on, until the n-1 record and the nth record's keywords have been compared. The above process is called the first bubbling sort, then the second trip to the previous n-1 the same operation, ...The quick

Bubble sort (Bubble sort) is a simple sort algorithm. Each time the adjacent two numbers are compared, they are exchanged if their positions do not match.Each comparison, the number of comparisons will be reduced one time, because

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 ar

Bubble Sort Method : A record of a small number of keywords is like a bubble stepping up, the key word larger record is like a stone sinking, each trip has one of the largest stones to the bottom. Algorithmic Nature: (The maximum is the key point, must be put to the last, so the cycle) each time from the first backward scrolling comparison, so that the maximum v

first, the basic idea: Bubble sort is a simple sort of commutative class. The basic idea is to scan the elements that are to be sorted from scratch, to compare the adjacent elements in sequence during the scan, and to move the elements of the key value back. After each trip, the element with the largest key value is moved to the end, and the position of the elem

Java selects sort and bubble sort, java selects sort bubble Characteristics and differences between sorting and Bubble Sorting ++ ++

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
