In this Set mutations problem, You are given a set A and N number of other sets. These N number of sets have to perform some specific mutation operations on set A. Your task is to execute those operations and print the sum of elements from set A.

## Problem solution in Python 2 programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
raw_input()
s = set(map(int,raw_input().split()))
n = int(raw_input())
for _ in range(n):
exec "s." + raw_input().split() + "(map(int,set(raw_input().split())))"
print sum(s)```

## Problem solution in Python 3 programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT

if __name__ == '__main__':
(_, A) = (int(input()),set(map(int, input().split())))
B = int(input())
for _ in range(B):
(command, newSet) = (input().split(),set(map(int, input().split())))
getattr(A, command)(newSet)

print (sum(A))```

```# Enter your code here. Read input from STDIN. Print output to STDOUT
(_, A) = (
raw_input(),
set(map(int, raw_input().split()))
)

for _ in xrange(input()):
(command, newSet) = (
raw_input().split(),
set(map(int, raw_input().split()))
)

getattr(A, command)(newSet)

print sum(A)```

### Problem solution in pypy3 programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
n = input()
s = set(map(int, input().split()))

for _ in range(int(input())):
args = input().strip().split()
nw= set(map(int, input().split()))
eval("s." + args + "(  nw  )")
print(sum(s))```
