                     1.1  Coding
                     1.2  Decoding
                     1.3  Puzzle Test

                     Dear students, in this chapter, we will do mental exercise to understand a problem and
                     decode it. This process of decoding of a complex problem requires critical and analytical
                     thinking. Reading of problem, understanding it and finding its solution is the overall objective.
                     One problem may have many solutions and each programmer may solve it differently.

                     1.1 CODING
                     ‘Coding’ is a method of conveying a message in a secret way.

                     1.2 DECODING
                     ‘Decoding’ is a process to break the code to understand the conveyed message. It is process

                     of analyzing and interpreting the message.

                                Hey! Do you know                 Actually, it is a                  In this code, each

                                 the meaning of                 coded form of a                     letter is one place
                                the encoded word              word. To understand                     ahead from its
                                                              its meaning, we have
                                      ‘TVO’?                      to decode it.                        original place.

                                                                                                        Let me do:

                                                                                                         T  V   O

                                  This word does        How???                                           S  U  N
                                 not make sense.                                                    Oh ! TVO means

                                                                                                          SUN.
