| Decode the Mad man | |
| Once in BUET, an old professor had gone completely mad. He started talking with some peculiar | |
| words. Nobody could realize his speech and lectures. Finally the BUET authority fall in great trouble. | |
| There was no way left to keep that man working in university. Suddenly a student (definitely he was | |
| a registered author at UVA ACM Chapter and hold a good rank on 24 hour-Online Judge) created | |
| a program that was able to decode that professor’s speech. After his invention, everyone got comfort | |
| again and that old teacher started his everyday works as before. | |
| So, if you ever visit BUET and see a teacher talking with a microphone, which is connected to a | |
| IBM computer equipped with a voice recognition software and students are taking their lecture from | |
| the computer screen, don’t get thundered! Because now your job is to write the same program which | |
| can decode that mad teacher’s speech! | |
| Input | |
| The input file will contain only one test case i.e. the encoded message. | |
| The test case consists of one or more words. | |
| Output | |
| For the given test case, print a line containing the decoded words. However, it is not so hard task to | |
| replace each letter or punctuation symbol by the two immediately to its left alphabet on your standard | |
| keyboard. | |
