If you ordered the OTS package, you don’t need installation so you can skip next chapter. When booting, MME and eNB are automatically started within a screen. If you are not familiar with screen here is what you must know: • To have access to consoles, log on the machine with root access, then type: screen -r • To access MME monitor: CTRL-A + 0 • To access eNB monitor: CTRL-A + 1 • To exit screen: CTRL-A + d

这段文字提供了一些关于 OTS 包的信息以及关于 screen 的使用方法。如果你已经订购了 OTS 包,那么你不需要进行安装,可以跳过下一章节。在启动时,MME 和 eNB 会自动在一个 screen 中启动。如果你不熟悉 screen,你需要知道以下几点:
- 要访问控制台,请使用 root 权限登录到机器上,然后输入:screen -r。
- 要访问 MME 监视器,请按下 CTRL-A + 0。
- 要访问 eNB 监视器,请按下 CTRL-A + 1。
- 要退出 screen,请按下 CTRL-A + d。
这些快捷键可以让你在 screen 中轻松地切换控制台和退出 screen。

What are the possible values of the list-style-type property when it is used with ordered lists?
The possible values of the `list-style-type` property when used with ordered lists are:
1. `decimal` (default) - Numbers from 1 to 10, then 11 to 20 and so on.
2. `decimal-leading-zero` - Numbers from 01 to 10, then 11 to 20 and so on.
3. `lower-roman` - Lowercase Roman numerals (i, ii, iii, iv, v, etc.).
4. `upper-roman` - Uppercase Roman numerals (I, II, III, IV, V, etc.).
5. `lower-greek` - Lowercase Greek letters (α, β, γ, δ, ε, etc.).
6. `lower-latin` - Lowercase Latin letters (a, b, c, d, e, etc.).
7. `upper-latin` - Uppercase Latin letters (A, B, C, D, E, etc.).
8. `lower-alpha` - Lowercase alphabetical letters (a, b, c, d, e, etc.).
9. `upper-alpha` - Uppercase alphabetical letters (A, B, C, D, E, etc.).
For example, to set an ordered list to display uppercase Roman numerals, you would use the following CSS:
```
ol {
list-style-type: upper-roman;
}
```
2. (2 points) Please find the dates without any placed order between the time range. (Hint: write a recursive query to create date sequence and use the select statement in Q1 to assign user-defined variables so that you can have a neat recursive query.)
Assuming that the table containing placed orders is called `orders` and has a column `order_date` of type DATE, the recursive query to generate a sequence of dates within a time range and then find the dates without any placed order would look like this:
```
WITH RECURSIVE dates(dt) AS (
SELECT start_date FROM (SELECT DATE('2022-01-01') AS start_date) vars
UNION ALL
SELECT dt + INTERVAL 1 DAY FROM dates WHERE dt < '2022-12-31'
)
SELECT dt FROM dates
WHERE dt NOT IN (
SELECT DISTINCT DATE(order_date) FROM orders
WHERE order_date BETWEEN '2022-01-01' AND '2022-12-31'
)
ORDER BY dt;
```
In this query, the recursive CTE `dates` generates a sequence of dates starting from January 1st, 2022 and ending on December 31st, 2022. The main query then selects all dates from this sequence that are not present in the `orders` table within the specified time range. The `DISTINCT` keyword is used to remove any duplicate dates from the `orders` table, and the `DATE()` function is applied to the `order_date` column to extract only the date part. Finally, the result is ordered by date in ascending order.
