2选择排序(selection sort) 选择排序是从未排序数列中选择最小的数,存放到排序数列中的起始位置,然后再选出第二小的数,附在已排序数列的最后。这样我们就可以将数列从小到大地进行排序。算法终止的条件是遍历完原数列。我们每次操作需要在原数列中比较O(n)次,共执行n次,算法的时间复杂度为O(n^2)。
选择排序(Selection sort)是一种简单直观的排序算法。 它的工作原理如下。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。 插入排序(英语:Insertion Sort)是一种简单直观的排序算法。

In computer science, sorting is arranging elements in an ordered sequence. Over the years, several algorithms were developed to perform sorting on data, including merge sort, quick sort, selection sort, or bubble sort. (The other meaning of sorting is categorizing; it is grouping elements with ...
