Question 1 (35 marks) Two friends are exchanging messages through regular post mail. They don't want anyone to understand their messages in case anyone read them. The messages are in the form of an array of characters, where each character has a numeric value as illustrated in the below lookup table. A В D E F G H J K M 2 3 4 10 11 12 13 1 7 8 N PQR S TU V w X Y 14 15 16 | 17 18 19 20 21 22 23 24 25 26 They decided to change the characters in the array in a way that cannot be observed by any accidental reading. They do so as follows: 1- Given the original message, for example: GREETINGS 2- transform the original character to its numeric value 7 18 5 5 20 9 14 7 19 3- For each number, subtracting from its value the value of the first lower value character after it, and if there's no such character they will keep that character without any change. 2 13 5 5 11 2 7 7 19 7 18 5 5 20 9 14 7 19 2 13 5 5 11277 19 7 18 55 20 9 14 7 19 7-5 = 2 7 18 55 20 9 14 7 19 18-5 = 13 7 18 55 20 9 14 7 19…
