                    Recap


                          An algorithm is a set of step-by-step instructions in a sequential manner to solve a
                        problem.
                          The  raw  data  is  collected,  filtered,  sorted,  processed,  analysed,  stored,  and  then
                        presented in a readable format, called information.
                          Conditional statements are used in a program to instruct the computer to make a
                        decision.
