插入排序Insertion Sort

插入排序:将一个数据插入到一个已经排好序的有序数据序列中,从而得到一个新的、个数+1的有序数列;插入排序适用于少量数据排序,时间复杂度为O(n^2)。实现思路:1.对于一个无序数组,选取第一个元素,看作一个有序数组     2.从第二个元素开始,插入到前面的有序数列     3.插入时,从有序数列的倒序开始,进行大小判...

插入排序——Insertion Sort

1、原理:从整个待排序列中选出一个元素插入到已经有序的子序列中去,得到一个有序的、元素加一的子序列,直到整个序列的待插入元素为0,则整个序列全部有序。2、思路:   (1)设置监视哨r[0],将待插入的记录值赋值给r[0];  (2)设置开始查找的位置j;  (3)在数组中搜索,搜索中将第j个记录后移,直到r...
