We have seen the applications of *union, intersection, difference* and *symmetric difference* operations, but these operations do not make any changes or mutations to the set.

**We can use the following operations to create mutations to a set:**

**.update()** or `|=`

Update the set by adding elements from an iterable/another set.

```
>>> H = set("Hacker")
>>> R = set("Rank")
>>> H.update(R)
>>> print H
set(['a', 'c', 'e', 'H', 'k', 'n', 'r', 'R'])
```

**.intersection_update()** or `&=`

Update the set by keeping only the elements found in it and an iterable/another set.

```
>>> H = set("Hacker")
>>> R = set("Rank")
>>> H.intersection_update(R)
>>> print H
set(['a', 'k'])
```

**.difference_update()** or `-=`

Update the set by removing elements found in an iterable/another set.

```
>>> H = set("Hacker")
>>> R = set("Rank")
>>> H.difference_update(R)
>>> print H
set(['c', 'e', 'H', 'r'])
```

**.symmetric_difference_update()** or `^=`

Update the set by only keeping the elements found in either set, but not in both.

```
>>> H = set("Hacker")
>>> R = set("Rank")
>>> H.symmetric_difference_update(R)
>>> print H
set(['c', 'e', 'H', 'n', 'r', 'R'])
```

**TASK**

You are given a set and number of other sets. These number of sets have to perform some specific mutation operations on set .

Your task is to execute those operations and print the sum of elements from set .

**Input Format**

The first line contains the number of elements in set .

The second line contains the space separated list of elements in set .

The third line contains integer , the number of other sets.

The next lines are divided into parts containing two lines each.

The first line of each part contains the space separated entries of the *operation name* and the *length of the other set*.

The second line of each part contains space separated list of elements in the other set.

*len(set( A))*

*len(otherSets)*

**Output Format**

Output the sum of elements in set .

**Sample Input**

```

1 2 3 4 5 6 7 8 9 10 11 12 13 14 24 52
4
intersection_update 10
2 3 5 6 8 9 1 4 7 11
update 2
55 66
symmetric_difference_update 5
22 7 35 62 58
difference_update 7
11 22 35 55 58 62 66
```

**Sample Output**

```
38
```

**Explanation**

After the first operation, (*intersection_update operation*), we get:

set

After the second operation, (*update operation*), we get:

set

After the third operation, (*symmetric_difference_update operation*), we get:

set

After the fourth operation, ( *difference_update operation*), we get:

set

The sum of elements in set after these operations is .
