[Tutor] where I am going wrong?

Suggestions for potentially simpler and more efficient code.

Create a ruple of the 5th powers of the 10 digits and look them up 
(should be faster than recomputing the 5th power each time) (0, 1, 16, ... )

Instead of trying all permutations of digits, use combinations. 12345 
will yield the same sum-of-5th-powers  as 23154. Compute the sum then 
see if it is composed of the source digits.
