Problem 8

A long string of ciphertext resulting from a Hill cipherC1 aP1 + bP2 (mod 26)C2 - cP1 + dP2 (mod 26)revealed that the most frequently occurring two-letter blocks were HO and PP, in thatorder.(a) Find the values of a, b, c, and d.[Hint: The most common two-letter blocks in the English language are TH, followedby HE.](b) What is the plaintext for the intercepted message PPIH HOG RAPVT?
