说明：  实现顺序表的以下基本操作 1.创建一个顺序表 2.向顺序表中插入元素 3.删除顺序表中的某个元素 4.查找顺序表中的元素（按值找、按序号找） 5.输出顺序表中的元素 注意观察分析所写算法的复杂度
(The following basic operations to implement the sequence table 1. create a sequence table 2. insert elements into the sequence table 3. delete an element in the order table 4. find the elements in the sequence table (find by value, look for the serial number) 5. elements in the output sequence table Pay attention to the complexity of the algorithm written by the observation and analysis)
