*
* Arguments:   - uint32_t p[N]: input/output coefficient array

* Name:        invntt_tomont

* Description: Inverse NTT and multiplication by Montgomery factor 2^32.
*              In-place. No modular reductions after additions or
*              subtractions; input coefficients need to be smaller than
*              Q in absolute value. Output coefficient are smaller than Q in
*              absolute value.
