对常用的内部排序算法进行比较：直接插入排序、简单选择排序、冒泡排序、快速排序、希尔排序（在教科书中，各种内部排序算法的时间复杂度分析结果只给出了算法执行时间的阶，或大概执行时间。试通过随机数据比较各算法的关键字比较次数和关键字移动次数，以取得直观感受。）-Internal sorting algorithm commonly used for comparison: direct insertion sort, simple selection sort, bubble sort, quick sort, Hill (in textbooks, various internal sorting algorithm time complexity analysis gives only the execution time of the algorithm The order, or about the execution time. trial comparing the data through random algorithms compare the number of keywords and keyword number of moves to get an intuitive feel.)
