n = int(input())
list_name = list(map(str, input().split()))
m = int(input())
vote_name = list(map(str, input().split()))

valid_count = 0
for name in list_name:
    valid_count+=vote_name.count(name)
    print(name+ ' : '+ str(vote_name.count(name)))

print('Invalid : '+ str(m-valid_count))

统计投票中候选人票的数量： vote_name.count(name)

统计有效票数：valid_count+=vote_name.count(name)
