顺序标的相关操作，如（1）  清除线性表L中多余的重复元素

（2）已知两个线性表LA和LB中的数据元素按非递减有序排列，现要求将LA和LB归并为一个新的线性表LC，且LC中的数据元仍按值非递减有序排列。（1）  清除线性表L中多余的重复元素

（2）已知两个线性表LA和LB中的数据元素按非递减有序排列，现要求将LA和LB归并为一个新的线性表LC，且LC中的数据元仍按值非递减有序排列。

（3）利用两个线性表LA和LB分别表示两个集合A和B，求集合A=AUB。

（3）利用两个线性表LA和LB分别表示两个集合A和B，求集合A=AUB。-Related to the operation of the order of the subject, such as (1) Clear the linear form L in excess of repeat elements (2) known ordered arrangement of two linear tables in LA and LB data elements according to non-decreasing, hereby request that the LA and LB merge into a new linear table LC, and the the LC data based upon the value of the non-decreasing ordered arrangement. (1) Clear the linear form L in excess of repeating elements (2) known two linear list of data elements in the LA and LB orderly arranged in non-decreasing, LA and LB are now required to merge as a new line of the table LC and LC in the data element based upon the value of non-decreasing ordered arrangement. (3) the use of two linear table LA and LB denote two sets A and B, A = AUB seeking collection. (3) the use of two linear table LA and LB denote two sets A and B, A = AUB seeking collection.
