   // 從切片中刪除元素
   func SliceDelete() {
   	// 初始化一個(gè)新的切片 seq
   	seq := []string{"a", "b", "c", "d", "e", "f", "g"}

   	// 指定刪除位置
   	index := 3

   	// 輸出刪除位置之前和之后的元素
   	fmt.Println(seq[:index], seq[index+1:])
   	// seq[index+1:]... 表示將后段的整個(gè)添加到前段中
   	// 將刪除前后的元素連接起來(lái)
   	seq = append(seq[:index], seq[index+1:]...)
   	// 輸出鏈接后的切片
   	fmt.Println(seq)
   }
   
OutPut Result:
[a b c] [e f g]
[a b c e f g]
