注意事项:

参考代码:

n = int(input())

l = list(input().split())

a = b = c = d = 0

for i in l:

    if 0 <= int(i) <= 18:

        a += 1

    elif 19 <= int(i) <= 35:

        b += 1

    elif 36 <= int(i) <= 60:

        c += 1

    else:

        d += 1

t = [a,b,c,d]

for i in t:

    print("{:.2f}%".format((i/n)*100))
