In a two-stage coding system, the first stage provides (7, 4) coding while the second stage supports (11, 7) coding. Is it better to have such a two-stage coding scheme as compared to a single-stage (11, 4) complex coding? Explain your answer in terms of the algorithmic complexity and error correcting capabilities.
