Example 4: Write an algorithm and draw a flowchart to calculate the factorial of a number.

                                 Algorithm:                                Flowchart:
                 Step 1   Start.
                                                                              Start
                 Step 2   Read the number N.
                                                                             Read N
                 Step 3   Let I=1, FACT=1

                 Step 4    Check If I < = N Then Repeat Step
                                                                         I = 1, Fact = 1
                          5 and 6 until I=N

                 Step 5   FACT=FACT*I
                                                                               If         No
                 Step 6   I=I+1                                              I < = N

                 Step 7   Print FACT                                              Yes

                 Step 8   End.                                           FACT = FACT*I
                                                                                                    Print FACT

                                                                            I = I + 1



                                                                              Stop

                 Mind Map

                 A  Mind  Map  is  also  a  problem-solving  technique  that  allows  us  to  organise  ideas,  thoughts  or
                 concepts and their relationship in a graphical manner.
                 In this technique, we pick up the ideas that have common features. These ideas are then grouped
                 under  one  category,  and  the  different  categories  are  linked  to  the  main  topic  using  lines  or
                 arrows.
