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.

Chapter 2 Basic Search Algorithms Data search is a basic computer programming task and has been studied for many years. This chapter only studies one aspect of finding a problem-finding a given value in the list (array. There are two basic methods to search data in the list: sequential search and binary search. The ordered search applies when the items in the lis
