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                        i = 1, fact = 1
                          Step 5 and 6 until i=n

                 Step 5:  fact=fact*i                                               Is
                                                                                   i < =     No
                 Step 6:  i=i+1                                                     n?

                 Step 7:  Print fact                                                   Yes

                 Step 8:  Stop.                                                fact = fact*i
                                                                                                          Print fact
                                                                                 i = i + 1



                                                                                   Stop

                 MIND MAPS


                 A Mind Map is a also a problem-solving technique that allows us to organise ideas, thoughts, or concepts
                 and their relationship graphically.
                 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.
