Insertion sort uses N^2/4 compares and N^2/4 exchanges to sort a randomly ordered array of length N with distinct keys, on the average. The worst case is N^2/2 compares and N^2/2 exchanges and the best case is N-1 compares and 0 exchanges. 证明过程给出书中的原文: Proof: Justas...

之前我们已经介绍过冒泡排序 Bubble Sort: zhuanlan.zhihu.com/p/38 以及选择排序Selection Sort:zhuanlan.zhihu.com/p/38 选择排序的算法原理: 选择排序是先选定左边第一个位置,然后将其它元素和第一个位置的元素进行对比,如果右边的某个元素更小,那么将该元素与第一个位置的元素交换。 选择排序的第二趟:选定左边...

Selection Sort/Bubble Sort/Insertion SortOct 21, 2016 at 6:45pm amkir100 (4) I have a code that doesn't have any compile issues. However, when I try to run it, it's not working. Any help would be great, I am fairly new to this.123456789101112131415161718192021222324...
In this paper, we propose an efficient sorting algorithm known as Enhanced Bidirectional Insertion Sorting algorithm which is developed from insertion sort concept. A comparative analysis is done for the proposed Enhanced Bidirectional Insertion Sort algorithm with the selection sort and insertion sort ...
**选择排序算法:详见Selection Sort** 插入排序算法(Insertion Sort):非常适用于小数组和部分排序好的数组,是应用比较多的算法。详见本文 插入排序算法的语言描述: 大家都打过牌吧,理牌的时候,每人手里一把牌,一般都会按由大到小顺序排好,每抓一个新牌(比如 5),都会找到4和6,把6往后挪一下,然后把5插到4...
