SHOULD BE IN JAVA :)
Problem 1. Construct a hash function as follows. The input of the hash function is English which include 26 letters and the space. So we will compute in Z27. The input text will be divided into blocks of 25 letters, the output will be 5 letters. Use an array OUT [5] to store the output. Initialize OUT [5] with all O's. The hash process include 3 rounds: Round 1 Write the 25 letters as a row-wise 5 x 5 block text and covert it to numbers. For example, if the input is: "abcdefghi jklmnopqrstuvwx, then we have a b c d e 0 1 2 3 4 5 6 7 8 26 jkim 9 10 11 12 13 opa 14 15 16 17 18 t uvw 19 20 21 22 23 ol n S r 1 Add numbers in ith column in 227 and plus the resulting number to OUT [i] to update the value of OUT[i]. In this example, the updated value will be [20, 25, 3, 8, 3]. (e.g., 0+5+ 9 + 14 + 19 = 20 (mod 27). Since the previous value of UOT [0] = 0, the updated value is 0 + 20 = 20 (mod 27).). Problem 1.
