Indeed, if there was a smaller compression than $k$, than the prefix function at the end would be greater than $n - k$. -Therefore $k$ has is really the answer. +Therefore $k$ is really the answer. Now let us assume that $n$ is not divisible by $k$. We show that this implies that the length of the answer is $n$.
