Sorting refers to arranging the collection of elements in the specified order. There are usually two sorts of sorting methods, ascending and descending. For example, the integer set {5,2,7,1} is sorted in ascending order, the result is {1,2,5,7}, and the result is {7,5,2,1} in descending order. In general, the purpose of sorting is to make the data appear in a more meaningful way. Although the most significant sort of application is arranging

point is reachedThe general tree does not ask the most deep is to traverse itThe hierarchical traversal sequence is a good follow-up. If you're going to spend the tree, ask him for a piece of paper. Give him the simplest logic 123456789.But web development is generally not too deep, think more about the technical point of not knowing what to say don't know nothing embarrassing.Well, that's a pretty general idea. I'm going to take the university's algorithm introduction and algorithm 4 out of th

, this time will not be faster than bubble sorting.Back to top 4, summaryThe above three kinds of sorting, bubbling, selecting, inserting with large O notation all require O (N2) time level. Bubbling sorting is not generally selected, although bubbling sort writing is the simplest, but the average performance is not to choose sort and insert sort well.Select sort to reduce the number of exchanges to the lowest, but the number of comparisons is quite large. Select sort can be applied when the amo

Select sort can be applied when the amount of data is small and exchange data is more
