实现了顺序表的建立，插入，删除等操作，还有两个集合的交并，及归并。-The order table creation, insert, delete, and other operations, and there are two sets of cross and merge.

设顺序表va中的数据元素递增有序。试写一算法，将x插入到顺序表的适当位置上，以保持该表的有序性。(Set the data elements in sequential table VA in ascending order. Try writing an algorithm to insert x into the appropriate place in the order table to keep the table in order.)
