In a networking system, logical gates are used to enable or disable the data to pass through them. The gates are used in pairs. One gate is for enabling data transfer and the other gate is for disabling data transfer. Each gate is denoted by a unique ID in the system from 0 to N- 1 and gates are tagged by their system IDs. System IDs can be positive .or negative numbers. A new feature is to be added in the system to automatically verify if all the gates are present in pairs i.e. paired gates have same system IDs. If a gate is not present in a pair, then output its system ID. Write an algorithm for the new feature to output the system ID of the gate which is not present in a pair.

Question
In a networking system, logical gates
are used to enable or disable the
data to pass through them. The
gates are used in pairs. One gate is
for enabling data transfer and the
other gate is for disabling data
transfer. Each gate is denoted by a
unique ID in the system from 0 to N-
1 and gates are tagged by their
system IDs. System IDs can be
positive or negative numbers. A new
feature is to be added in the system
to automatically verify if all the gates
are present in pairs i.e. paired gates
have same system IDs. Ifa gate is not
present in a pair, then output its
system ID.
Write an algorithm for the new
feature to output the system ID of
the gate which is not present in a
pair

Input
The first line of the input consists of
an integer-num, representing the
number of logical gates used n the
system (N).
The second line consists ofN space-
separated integers- sysiD, sysID,
sysIDN representing the
system IDs of the logical gates
present in the system, respectively.
Output
Print an integer representing the
system ID of the logical gate which is
not present in a pair.
