Example 1: Four children P, Q, R, and S are sitting on a bench. P is to the left of R, and Q
                  is third to the right of S. Who is sitting at the extreme right end?

                                                S            P            R           Q


                  Therefore, from above sitting arrangement it is clear that Q is sitting at extreme right
                  position.

                  Let us revise what we have learnt:

                     Coding is a method of conveying a message in a secret way.

                     Decoding is the process of breaking the code to understand the conveyed message.
                     A puzzle is a problem in which the information is given in a confusing and jumbled

                       manner.
