利用桶排序给数组a排序，建立的桶为b和e，其中b为含有十万个桶，e为只有一个链表的桶，然后对b和e使用插入算法排序，比较两种算法的时间，b需要40毫秒左右，e需要9到10分钟。-use barrels a ranking to the array, in order to establish the barrels of b and e, b to contain 100,000 barrels of only one e Chain barrels, and then to b e used to insert sorting algorithm, the algorithm for comparing two hours, b needs about 40 milliseconds, e needs 9 10 minutes.
