I tried googling, but I may not be searching with correct terms.
$$\sum_{k=1}^{n} k^k = 1^1 + 2^2 +3^3 + 4^4 + \cdots + n^n$$
So, is there a formula to calculate this?

1@StubbornAtom I guess most people refer to google over the search option on this site. :/ – Simply Beautiful Art Aug 16 '16 at 00:28
