书中共介绍了四类排序函数：插入排序、起泡排序、选择排序、快速排序。我们需要建立一个无序随机序列，分别用上述排序方法对建立的无序序列有序化，编写相应的程序计算每种算法的赋值次数、比较次数以及所用时间，以此为依据来判断各种算法的效率。-introduced a total of four ranking functions : insertion sort, bubble sort, select, in order of Quick Sort. We need to build a disorderly random sequence, the use of such methods of sequencing to establish an orderly sequence of the disorder, and the preparation of the corresponding procedures of each algorithm for the calculation of frequency assignment, as well as comparison with the number of time, using this as the basis to judge the efficiency of algorithms.
