Question 8

Let $z_1,$ $z_2,$ $z_3,$ $\ldots,$ $z_{12}$ be the $12$ zeroes of the polynomial $z^{12} - 2^{36}.$ For each $j,$ let $w_j$ be one of $z_j$ or $\mathrm{i}z_j.$ Then the maximum possible value of the real part of $\sum_{j=1}^{12} w_j$ can be written as $m + \sqrt{n},$ where $m$ and $n$ are positive integers. Find $m + n.$
