[鏈表練習2-1]線性表ADT的實現之一：線性表ADT基於順序存儲的實現

實習題目：線性表ADT實現之一：線性表ADT基於順序存儲的實現

實習目的：幫助學生熟練掌握順序表的建立及基本操作
問題描述：設計一個順序表並實現對其進行基本操作。
基本要求：建立一個順序表：
（1）輸入數據；
（2）實現數據的插入、刪除、搜索、輸出等基本操作；
（3）實現集合的並、交和兩個有序順序表的合併。

 

	測試輸入	期待的輸出
測試用例	5 1 3 5 7 9 2 10 10 9 22 6 1 2 3 4 5 6	A is created as: 1 3 5 7 9 After inserted A is 1 10 3 5 7 9 After deleted A is 1 3 5 7 9 9 is located at index of 5 22 is not found B is created as: 1 2 3 4 5 6 A cross B is 1 3 5 A union B is 1 3 5 7 9 2 4 6 A union B in sequence is 1 2 3 4 5 6 7 9

測試數據：

5  //線性表A的長度
1 3 5 7 9  //線性表A的數據
2 10 //表示在第2個位置插入10
10 //表示刪除值=10的數據元素
9 //查找元素9
22/ 查找元素22
6 //線性表B的長度

1 2 3 4 5 6
