please refund the question if you cannot answer this.

For the repetition code where each of the four messages {00, 01, 10, 11} is encoded by being transmitted 12 times ( so for example 01 would be transmitted as 010101010101010101010101)

For the code above answer: Is it linear? What is its block length, message length, rate and distance? How many errors can it detect, and how many can it correct? ( to answer this question you should give the largest number of errors that the code can guarantee to detect or correct. for example a simple parity bit can detect 1 or 3 errors but cannot detect 2 errors so we would say this can detect only a single error. no calculations of probability are required. STATE WITH JUSTIFICATION.
