Step 1: Understand the tripleu002Drepetition code.u000AThe tripleu002Drepetition code takes a binary message

The triple-repetition code (see page 102) is not a polynomial code but can be described as encoding the polynomial $p(x)$ by the polynomial $\left(1+x+x^2\right) p\left(x^3\right)$. Verify both parts of this statement.
