选择排序(Selection-sort)是一种简单直观的排序算法。它的工作原理:首先在未排序序列中找到最小(大)元素,存放到排序序列的起始位置,然后,再从剩余未排序元素中继续寻找最小(大)元素,然后放到已排序序列的末尾。以此类推,直到所有元素均排序完毕。 算法描述 n个记录的直接选择排序可经过n-1趟直接选择排序得到有序结...

Sorting is arranging elements in an ordered sequence. Over the years, several algorithms were developed to perform sorting on data; for instance merge sort, quick sort, selection sort, or bubble sort. (Another meaning of sorting is categorizing: grouping elements with similar properties.) ...

If your program is excellent and valuable for the users, they will use it after this step. They will see that it works and can do what it is supposed to do. Before the installation, however, this is a bit different. Users will install the program if they really, really need it. ...
