Sorting method can be divided into insertion sort, exchange sort, selection sort, merge sort four categories, and their performance analysis parameters Zeyi time complexity, space complexity and stability oriented.Which is sort of the quick sort method for exchanging the average time most provinces, but not as good as in the worst case heap sort and merge sort, heap sort and merge sort in time and space required as complementary situation; several time complexitydegree is O (n2) sorting is a simple advantage in stability and the realization of the method is simple, orderly and in the sequence of basic objects to be sorted relatively few cases, direct insertion sort is the best sort; generally speaking, noWhich sort is an absolute advantage in different situations need to select the appropriate sorting method, if necessary to achieve the best results have been mixed. The demonstration system consists of sorting algorithm called C-complete graph windows API programming, broken and solid lines with data lines and operating lines transform the mobile interactive demo to the timer to refresh the image as a base to achieve dynamic presentation of the results.Software can also export the data in the sorting process and the sorted data, and show the current sort method performance parameters, maximizing the user-friendly human-computer interaction do.Rankin
