多关键字的排序是有一定的实用范围。例如：在进行高考分数处理时，除了对总分进行排序外，不同的专业对单科分数的要求不同，因此尚需在总分相同的情况下，按用户提出的单科分数的次序要求排出考生录取的次序。(1)假如代排序的记录数不超10000，表中记录的关键字数不超过5，各个关键字的范围均为0至100。按用户给定的排序的关键字的优先关系，输出排序的结果。(2)约定按LSD方法进行多关键字的排序。在对各个关键字进行排序时采用两种策略：其一是利用稳定的内部排序方法，其二是利用“分配”和“收集”的方法。并综合比较这两种策略。(3)数据由随机数产生器生产。

-multiple keywords is the sort of practical scope. For example : In dealing with the college entrance examination scores, in addition to scores of rank, different professional right Billing Division fraction of the requirements, it needs to score in the same circumstances, based on the scores of the Billing Division of the order of requests from candidates taking the order. (1) If the order substituting non-record number 10000, the table records keywords not exceeding 5, all keywords are the scope of 0-100. According to the user's keyword ranking priority, output sequencing results. (2) agreement on LSD methods of sequencing multiple keywords. All the right sort keyword used two strategies : One is the use of the internal stability of the ranking, second, it uses "allocation"
