    I have written down the steps      Let's try that               Yay! The ticket       Hmm, I know. It
                    that I think we should follow.      practically.                 got booked.           is a method for
                                                                                                           solving problem.

                  In our daily lives, we have to solve various problems by using different strategies. These strategies are
                  called problem-solving techniques. Some of these techniques are algorithms and mind maps.

                  ALGORITHM

                  An algorithm is a set of steps sequentially to solve a problem or to complete a task. These steps are the
                  foundation of a program. They are important to programming as recipes are for cooking.

                  Writing an Algorithm

                  The construction  of the Algorithm  is the stage that requires creative thinking  and  finding  the best
                  possible combination of steps to get the result. For example:

                  Example 1: Algorithm for going to the market to purchase a pen.
                  Step 1:    Start.

                  Step 2:    Check your wallet for cash.
                  Step 3:    Go to the market.

                  Step 4:    Go to the stationery shop.
