Turning Turtle Left or Right

                 By default, turtle is facing towards the right side. We can change the degree value to change
                 the heading direction.

                 A turtle can be turned in two directions: clockwise (right) or anti-clockwise (left).












                                 Clockwise (Right)                              Anti-Clockwise (Left)

                 There are two blocks that can be used to turn turtles:






                          This can turn the turtle right                     This can turn the turtle left
                    or clockwise by some degrees, say '90'.         or anti-clockwise by some degrees, say '90'.
