测试代码中,我们还用了python自带的sort方法,通过 "assert ssort.items == items" 一行语句是来验证我们的插入排序算法运行结果的正确性。并且加了timer,来比较我们的算法和python自带的sort方法的运行时间。 运行结果表明,排序的结果是一样的,和选择排序算法差不多,当数据量大的时候,运行性能比python自带的sort算法...

CAS 是 compare and swap 的缩写，即我们所说的比较与交换。CAS 操作包含三个操作数，分别是内存位置...
Few Unique ALGORITHM for i = 2:n, for (k = i; k > 1 and a[k] < a[k-1]; k--) swap a[k,k-1] → invariant: a[1..i] is sorted end DISCUSSION Although it is one of the elementary sorting algorithms with O(n2) worst-case time, insertion sort is the algorithm of choice...

As shown in the above illustration, we begin with the 2ndelement as we assume that the first element is always sorted. So we begin with comparing the second element with the first one and swap the position if the second element is less than the first. ...
1098 Insertion or Heap Sort (25分) 题目大意:给定一个序列,和进行了几轮(也可以为0轮)排序的序列,要求判断使用的是插入排序还是堆排序的方式,并采用该排序方式来输出下一轮排序结果。 这题需要掌握堆结构以及堆排序的代码实现、插入排序,这里不赘述堆排序的实现啦,有需要的话这里还是推荐中国大学mooc上浙大的《...
