測試範例

Example 1:

Input:
+------------+---------+-----+
| student_id | name    | age |
+------------+---------+-----+
| 32         | Piper   | 5   |
| 217        | None    | 19  |
| 779        | Georgia | 20  |
| 849        | Willow  | 14  |
+------------+---------+-----+
Output:
+------------+---------+-----+
| student_id | name    | age |
+------------+---------+-----+
| 32         | Piper   | 5   |
| 779        | Georgia | 20  | 
| 849        | Willow  | 14  | 
+------------+---------+-----+
Explanation: 
Student with id 217 havs empty value in the name column, so it will be removed.

這筆資料在name欄位有缺失值​，所以最後從資料表中刪除掉。
| 217 | None | 19 |
