Problem solving task

The airplane You are navigating an airplane, which can take a series of commands: • up X increases the direction by X units • down X decreases the direction by X units • forward X increases the horizontal position by X units and the vertical position by X multipled by the current direction Here is an example of a preplanned course: forward 4 up 2 forward 8 down 1 forward 2 up 3 forward 3 These instructions would do the following (with the initial position and direction set to 0): • Increase the horizontal position by 4 (as your direction is 0, the vertical position stays unchanged) • Increase the direction by 2 • Increase the horizontal position by 8 and vertical position by 16 (as the direction is 2, the vertical position becomes the previous value 0 + 2 * 8 = 16) • Decrease the direction by 1 • Increase the horizontal position by 2 and vertical position by 2 (as the direction is 1, the vertical position becomes the previous value 16 + 1 * 2 = 18) • Increase the direction by 3 • Increase the horizontal position by 3 and vertical position by 12 This course would result in a horizontal position of 17 and a vertical position of 30. Create a program that reads the preplanned course from a file (e.g. a file containing the preplanned course above), calculates the horizontal and vertical position after following the course and then multiplies the final horizontal position by the final vertical position. In this case that would be 17 * 30 = 510. Sumbit the code for calculating the above scenario. It should be • Easy to extend the code with additional commands, could for example be a dive command where “dive 4” would instantly decrease the vertical position by 4 • Unit tests • Readable code that is easy to follow
