数据结构之实现设置监视哨的顺序查找。实验内容：

1、完成初始化函数

2、完成插入顺序表的函数

3、完成查找函数

4、完成根据查找结果的输出函数

5、完成主函数-Data structure to achieve set lookout for sequential search. Experiment: a complete initialization function 2, complete the insertion sequence table function 3, complete the search function 4, and complete search results based on the output of the function 5, the completion of the main function
