ITP2_9の解答例(Python)

集合の演算に関する問題です．

1. ITP2_9_A: Set Union

# ITP2_9_A

n = int(input())
A = set(map(int,input().split(" ")))

m = int(input())
B = set(map(int,input().split(" ")))

# 和集合
C = sorted(A | B)
for x in C:
    print(x)

2. ITP2_9_B: Set Intersection

# ITP2_9_B

n = int(input())
A = set(map(int,input().split(" ")))

m = int(input())
B = set(map(int,input().split(" ")))

# 積集合
C = sorted(A & B)
for x in C:
    print(x)

3. ITP2_9_C: Set Difference

# ITP2_9_C

n = int(input())
A = set(map(int,input().split(" ")))

m = int(input())
B = set(map(int,input().split(" ")))

# 差集合
C = sorted(A - B)
for x in C:
    print(x)

4. ITP2_9_D: Set Symmetric Difference

# ITP2_9_D

n = int(input())
A = set(map(int,input().split(" ")))

m = int(input())
B = set(map(int,input().split(" ")))

# 互いに素な集合 和集合から積集合を引けばいい
C = sorted((A | B) - (A & B))
for x in C:
    print(x)
