Just checked it out and understood the question. Since my IDE(Sketchware mobile IDE) is like a drag and drop development environment, I'd consider solving this as a cheating to all java programmers out there who would scratch their brains and write the code from start. Using my IDE with some ASD(Add Source Directly) blocks/codes, I'd solve this in less than 3 hours |

mosesabah:Question Your country is at war and your enemies are using a secret code to communicate with each other. You have managed to intercept a message that reads as follows::mmZdxZmx]Zpgy The message is obviously encrypted using the enemy's secret code. You have just learned that their encryption method is based upon the ASCII code. Appendix 3 of your book shows the ACII character set. Individual characters in a string are encoded using this system. For example, the letter "A" is encoded using the number 65 and "B" is encoded using the number 66. Your enemy's secret code takes each letter of the message and encrypts it as follows:If(OriginalChar + Key > 126) then EncryptedChar = 32 + ((OriginalChar + Key ) - 127) else EncryptedChar = (OriginalChar + Key) For example, if the enemy used Key = 10 then the message "Hey" would be encrypted as:CharacterASCII Code H72 e101 y121 Encrypted H = (72 + 10) = 82 = R in ASCII Encrypted e = (101 + 10) = 111 = o in ASCII Encrypted y = (121 + 10) - 127 = 36 = $ in ASCII Consequently, "Hey" would be transmitted as "Ro$". Write a program that decrypts the intercepted message. You only know that the key used is a number between 1 and 100. Your program should try to decode the message using all possible keys between 1 and 100. When you try the valid key, the message will make sense. For all other keys the message will appear as gibberish. 1 Like |
