import math
r = int(input())
print(2 * r * math.pi)

n, m = map(int, input().split())
aaa = list(map(int, input().split()))
cnt = n - sum(aaa)
print(cnt if cnt >= 0 else -1)

n = int(input())
aaa = list(map(int, input().split()))
num = [0] * n
for a in aaa:
    num[a - 1] += 1
for n in num:
    print(n)
