I forget how to reverse the order of integration for triple integrals, here's the question.

Express the iterated integral

$\displaystyle \int_{-1}^{1} \int_{z^2}^1 \int_0^{1-y} g(x,y,z)dxdydz $

as an equivalent integral in which the y-integration is performed 1st, the z-integration second, and the x-integration last.

Thanks for any help.
