# Data Transfer
2+
3+
You will be given several lines of **messages containing data**. You have to **check for the validity of the lines**. A **valid** line should be in the format: **"s:{sender};r:{receiver};m--"{message} ""**
4+
5+
* **sender – **could contain **any ascii character except for ";"**
6+
7+
* **receiver –** could contain **any ascii character except for ";"**
8+
9+
* **message –** should contain **only letters and spaces**
10+
11+
In each valid message there is a **hidden size of data transfer.** The size of the data transfer is **calculated by the sum of all digits in the names of the sender and receiver**. After each valid message print a line in the format: "**{senderName} says "{currentMessage}" to {recieverName}". **The **printed names should contain only letters and spaces**. Example: sender “P@e$5sh#o Go^4sh5ov” is **valid **and **matches**, but when printing his name, **we only print** “Pesho Goshov”.
12+
13+
At the end print a line in the format **"Total data transferred: {totalData}MB"**.
14+
15+
## Input / Constraints
16+
17+
* First line will be a number **n** in range [1, 100].
18+
19+
* The next **n** lines will be **strings**.
20+
21+
## Output
22+
23+
* Print each valid message in the format described above.
24+
25+
* Print the total amount of data transfer.

# Tagram
2+
3+
You will receive **several input lines** in one of the following formats:
4+
5+
* **"{username} -> {tag} -> {likes}"**
6+
7+
* **"ban {username}"**
8+
9+
The **username **and** tag **are strings. **Likes** will be an integer number. You need to keep track of **every user**.
10+
11+
When you receive a **user**, a **tag** and **likes**, register the user if **he isn't present**, **otherwise add** the tag and the likes. If the user has already used the tag just add the likes to it.
12+
13+
If you receive **"ban {username}"** and **the username exists**, remove him from the database.
14+
15+
You should end your program when you receive the command **"end"**. At that point you should print the users, **ordered by total likes in desecending order, then ordered by the tags’ count in ascending order**. **Foreach** player print their tag and likes.
16+
17+
## Input / Constraints
18+
19+
* The input comes in the form of commands in one of the formats specified above.
20+
21+
* Username and tag **will always be one word string, containing no whitespaces**.
22+
23+
* Likes will be an **integer** in the **range [0, 1000]**.
24+
25+
* There will be **no invalid** input lines.
26+
27+
* The programm ends when you receive the command **"end"**.
28+
29+
## Output
30+
31+
* The output format for each player is:
32+
33+
**"{username}"**
34+
35+
**"- {tag}: {likes}"**
