In the third round, Jerry is at a higher level. Thus, the cycle goes
                  on.
                  Repeating a set of steps is called a loop.

                      UNDERSTANDING PROGRAMS

                  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





                      Recap



                         The process of completing one step and going onto the other is known as stepwise
                        thinking.

                         Decision making is a process of arriving at a conclusion by making a choice.
                          The act of repeating an action again and again is called looping.
