You intercept the message "sonafqchmwptvevy", which you know was enciphered using a hill 2-cipher. an earlier statistical analysis of a long string of intercepted cipher-text revealed that the most frequently occurring cipher-text digraphs were "kh" and "xw" in that order. you take a guess that those digraphs correspond to "th" and "he", respectively, since those are the most frequently occurring digraphs in most long plaintext messages on the subject you think is being discussed. find the deciphering matrix and state was the message is supposed to be
