               Create the given scene in Scratch.




























               Run the given script and get the output.
                a.                                                  b.

                                                                                  Century

                                                                     </>
                  The word DOOR is coded as 25. This is done by adding the positions of the
                alphabet  and  then writing  the result backwards.  So, DOOR=  4+15+15+18=52
                reverse of 52 gives 25.

                  Now, solve the following in the same way:

                a.  BOOK __________                           b.  MEDICINE __________
