* Description: Forward NTT, in-place. No modular reduction is performed after
*              additions or subtractions. Output vector is in bitreversed order.
*
* 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.
