建立一顺序表，实现其基本操作：新建一个顺序表；判断是否是空表；输入表的长度；输入线性表的各个数据元素的值；求当前表长；取某个位序上的数据元素；求某元素的前驱和后继；删除某个位置上的数据元素；求删除后的表长；置空表；销毁线性表。-Establish a sequence table to achieve its basic operations: create a sequence table　determine whether it is an empty table　length of the input table　enter values ​ ​ for each data element linear form　seek current table length　data elements take on a bit sequence　 seeking a predecessor and successor elements　delete data elements to a position　seeking to delete the table long after　blank sheet　destroy linear form.
