Problem: There are 3N participants in _AtCoder Group Contest_. The _strength_ of the i-th participant is represented by an integer a_i. They will form N teams, each consisting of three participants. No participant may belong to multiple teams.  The strength of a team is defined as the second largest strength among its members. For example, a team of participants of strength 1, 5, 2 has a strength 2, and a team of three participants of strength 3, 2, 3 has a strength 3.  Find the maximum possible sum of the strengths of N teams.

Problem: There are 3N participants in _AtCoder Group Contest_. The _strength_ of the i-th participant is represented by an integer a_i. They will form N teams, each consisting of three participants.

For example, a team of participants of strength 1, 5, 2 has a strength 2, and a team of three participants of strength 3, 2, 3 has a strength 3.

Problem: There are 3N participants in _AtCoder Group Contest_. The _strength_ of the i-th participant is represented by an integer a_i. They will form N teams, each consisting of three participants. No participant may belong to multiple teams.  The strength of a team is defined as the second largest strength among its members. For example, a team of participants of strength 1, 5, 2 has a strength 2, and a team of three participants of strength 3, 2, 3 has a strength 3.  Find the maximum possible sum of the strengths of N teams.

Submission attempts (in order):
n = int(input())
a = list(map(int, input().split()))
a.sort()
sum(a[n::2])

n = int(input())
a = list(map(int, input().split()))
a.sort()
print(sum(a[n::2]))
