# .remove(x)
# This operation removes element x from the set. 
# If element x does not exist, it raises a KeyError.
# The .remove(x) operation returns None.

# Example

# >>> s = set([1, 2, 3, 4, 5, 6, 7, 8, 9])
# >>> s.remove(5)
# >>> print s
# set([1, 2, 3, 4, 6, 7, 8, 9])
# >>> print s.remove(4)
# None
# >>> print s
# set([1, 2, 3, 6, 7, 8, 9])
# >>> s.remove(0)
# KeyError: 0
# .discard(x)
# This operation also removes element  from the set. 
# If element x does not exist, it does not raise a KeyError.
# The .discard(x) operation returns None.

# Example
# >>> s = set([1, 2, 3, 4, 5, 6, 7, 8, 9])
# >>> s.discard(5)
# >>> print s
# set([1, 2, 3, 4, 6, 7, 8, 9])
# >>> print s.discard(4)
# None
# >>> print s
# set([1, 2, 3, 6, 7, 8, 9])
# >>> s.discard(0)
# >>> print s
# set([1, 2, 3, 6, 7, 8, 9])
# .pop()
# This operation removes and return an arbitrary element from the set. 
# If there are no elements to remove, it raises a KeyError.

# Example
# >>> s = set([1])
# >>> print s.pop()
# 1
# >>> print s
# set([])
# >>> print s.pop()
# KeyError: pop from an empty set


# Task
# You have a non-empty set s, and you have to execute N commands given in N lines.
# The commands will be pop, remove and discard.

# Input Format
# The first line contains integer n, the number of elements in the set s. 
# The second line contains n space separated elements of set s. All of the elements are non-negative integers, less than or equal to 9. 
# The third line contains integer N, the number of commands.
# The next N lines contains either pop, remove and/or discard commands followed by their associated value.

# Constraints
# 0 < n < 20
# 0 < N < 20

# Output Format
# Print the sum of the elements of set s on a single line.

# Sample Input
# 9
# 1 2 3 4 5 6 7 8 9
# 10
# pop
# remove 9
# discard 9
# discard 8
# remove 7
# pop 
# discard 6
# remove 5
# pop 
# discard 5

# Sample Output
# 4

# Explanation
# After completing these 10 operations on the set, we get set([4]). Hence, the sum is 4.
# Note: Convert the elements of set s to integers while you are assigning them. To ensure the proper input of the set, we have added the first two lines of code to the editor.
