转换成字符串做

解题思路:

注意事项:最开始list里面的都是字符，用sort的时候记得转换成数字哈

参考代码:

n = int(input())

list0=[]

for i in range(100,1000):

    num1 = str(i) + str(i)[-2] + str(i)[-3]

    num2 = str(i) + str(i)[-1] + str(i)[-2] + str(i)[-3]

    list0.append(num1)

    list0.append(num2)

list1 = []

for i in list0:

    sum = 0

    for m in i:

        sum += int(m)

    if sum == n:

        list1.append(int(i))

list1.sort()

for i in list1:

    print(i)
