The relationship between 8 sorts: 1, direct insertion sort (1) Basic idea: In the set of numbers to be sorted, suppose that the front (n-1) [n>=2] number is already a row In a good order, now you have to insert the nth number into the preceding ordered number so that the number of n It's a good order, too. Repeat the loop until all the order is sorted. (2) Example (3) Implement with Java[Plain] View plain copy packagecom.njue; publicclassinserts

Direct Insert Sort:In the sequence , assume ascending sort1) start at 0.1) If you go to begin = 3, save the Begin element to TMP, compare the element at TMP with the element size relationship at begin--, and move the begin-1 element to begin if it is 3) and so on, go through the sequence sequentially.Complexity of Time: O ()The code is as follows: Sequence in ascending order void Insertsort (int* a,int size) {assert (a);for (int begin = 0; begin 2.

(n). Obviously, the smaller the bucket, the less data between buckets, and the less time it takes to sort. But the corresponding space consumption will increase.Best case: T (n) = O (n+k)Worst case: T (n) = O (n+k)Average condition: T (n) = O (n2)Three, Cardinal sort (Radix sort) (1) Introduction to AlgorithmsThe card

An algorithm is a set of well-defined rules that are used to solve a problem within a finite step. Popular point, that is, the process of computer problem solving. In this process, whether the formation of a problem-solving ideas or writing programs, are in the implementation of some kind of algorithm. The former is the algorithm of inference implementation, the latter is the algorithm of operation implementation. An algorithm should have the following five important features: 1. Poor: An algori

Select sortHow it works: each time the largest or smallest element is selected from the data element to be sorted, it is stored at the beginning of the sequence until all the data elements to be sorted are exhausted.Voidselectsort (int*a,size_tsize) {assert (a); for (inti=0;iHeap Sortonly needAscending Voidadjustdown (int*a,size_tsize,introot) { ASSERT (a);intchild=root*2+1; while (childThis article from "Write Quality or Low" blog, declined reprint!Sort
On the sorting method, the common sorting methods are insert sort, bubble sort, quick sort, select sort, merge sort, also have heap sort, bucket sort, base
12000000 (12 million) if it takes m=2500 (which saves a bit of space and has a high time efficiency).The sorting efficiency of buckets is also high.and the sorting algorithm for each bucket of buckets can also be changed to other not necessarily fast rows.The bucket sort app doesn't seem to be much, and it seems that a lot of people confuse the cardinal sort with the bucket sort.By contrast, the number of

The fast sorting method mainly utilizes a method of arrays to Arrays.sort () implementation. Bubble method is used to compare the traversal array, through the constant comparison of the minimum or maximum value of a single traversal. The Select Sort method is to use the first data of the array as the largest or smallest value, and then output the ordered array by comparing the loops. The insertion sort i
