Can't wait for next year!

With current computation speed, this problem can be solved well under a second even after expanding the whole thing. Here's my code:

1
2
3
4
5

>>> a = sum(int(x) for x in str(2015 ** 2015))
>>> b = sum(int(x) for x in str(a))
>>> c = sum(int(x) for x in str(b))
>>> a + b + c
29517

Solves in 0.002 sec.

First, it's a big number, but it's not difficult to solve the initial problem:

Now, assuming we're talking about the sum of the digits (as opposed to the AMOUNT of digits), we add all of those numbers together, and we can omit all zeroes. This is how we find A.

A =

Therefore A = 29,483

That's MUCH less intimidating. We follow the same strain of logic to compute B:

B = 2+9+4+8+3 = 26

And finally, C:

C = 2+6 = 8

Our goal doesn't involve the giant blocks of numbers; it involves A plus B plus C.

A+B+C = 29483+26+8 = 29517
