【程序29】 
题目：给一个不多于5位的正整数，要求：一、求它是几位数，二、逆序打印出各位数字。
1. 程序分析：学会分解出每一位数
2.程序源代码：
'''
x = int(input("input a number:\n"))
a = x // 10000
b = x // 1000
c = x // 100 % 10
d = x // 10 % 10
e = x % 10


if a != 0:
    print ("there are 5 ",e,d,c,b,a)
elif b != 0:
    print ("there are 4 ",e,d,c,b)
elif c != 0:
    print ("there are 3 ",e,d,c)
elif d != 0:
    print ("there are 2 ",e,d)
else:
    print ("there are 1",e )
