# 2016 Digital Root

For each number $$n$$, we define the Digital Root of $$n$$ in the following manner: Take the sum of the digits to obtain a new number. Repeat this process until the result is a single digit.

Find the digital root of $$\underset { 2016\text{ times} }{ \underbrace { 2016\ldots2016 } }$$.

As an explicit example, for $$n=3487$$, $3487\quad \rightarrow \quad 3+4+8+7=22\quad \rightarrow \quad 2+2=4 \; .$ Therefore, the digital root of 3487 is 4.

Clarification: In the number above, 2016 appears 2016 times in its decimal representation.
