Create a correctable code for a list of key words.  Your task is to create an efficient, correctable code for a list that contains 20 key words.  The words in your code will be represented as binary strings using only 0’s and 1’s.  Stringent correctability requirements mean your code must have a minimum distance of 3.- Create a code consisting of binary codewords.- The code must meet three requirements– Contain at least 20 codewords– Have a minimum distance of 3 (explain why a min distance of 4 is no better than 3)– Maintain efficiency by using the fewest number of bits per codeword as possible- Clearly document and describe your code: what it is, why you chose it, etc.- Discuss how topology relates to the selection of your code and the Hamming metric
