Problem 30

Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits:

1634 = 1 4 + 6 4 + 3 4 + 4 4
8208 = 8 4 + 2 4 + 0 4 + 8 4
9474 = 9 4 + 4 4 + 7 4 + 4 4

As 1 = 14 is not a sum it is not included.

The sum of these numbers is 1634 + 8208 + 9474 = 19316.

Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.


resu=0
for i in range(2,1000000):
	temp=0
	b = i
	while b>0:
		a = b%10
		b /= 10
		temp += a**5
	if temp==i :
		resu += i
print resu


看错题目 以为范围只是局限于5位数,浪费了20多分钟
