蓝桥杯2024年第十五届省赛真题-封闭图形个数

解题思路:

注意事项:

参考代码:

n = int(input().strip())

l = list(map(int,input().strip().split()))

l.sort()

l0 = [1,2,3,5,7]

l1 = [0,4,6,9]

l2 = [8]

t = []

def count(x):

    c = 0

    while x > 0:

        t = x % 10

        if t in l1:

            c += 1

        elif t in l2:

            c += 2 

        else:

            c += 0

        x = x // 10

    return c

for i in l:

    c = count(i)

    g = [i,c]

    t.append(g)

t.sort(key=lambda x:x[1])

for i in t:

    print(i[0],end=" ")
