In the second round, Harry and Jerry are both at the same

                                            level.






                 In the third round, Jerry is at a higher level. Thus, the cycle

                 goes on.                                                                                                   STEPWISE THINKING

                 Repeating a set of steps is called a loop.





                  Understanding Programs

                                                                                                                          81
                 A computer understands step-by-step instructions written only in a unique language,
                 called as program. The computer reads the program we write and follows as per our

                 instructions.

                 Let's write the steps to make a square.





                    Move 2 steps right.

                    Move 2 steps up.


                    Move 2 steps left.

                    Move 2 steps down.


                                                                                      Start

                 Similarly, we can write the steps to make a rectangle.




                    Move 2 steps right.

                    Move 1 step up.

                    Move 2 steps left.

                    Move 1 step down.                                                 Start
