pub fn ntt(f: &mut [i32; 256])Expand description
Forward NTT (Algorithm 41 of FIPS 204).
Transforms a polynomial f from the standard domain to the NTT domain
in place. Input coefficients should be in [0, q-1]; output coefficients
are also in [0, q-1].
After this call, f represents the evaluation of the original polynomial
at the 256 roots of unity used by ML-DSA.
