Moving the point on the coordinate plane

You should implement the Task.movePoint() method which takes the next arguments: Point pont and String[] commands. The point contains the initial coordinates where all transformations should start from. The commands array contain a list of point's coordinates transformations. The method should apply all transformation from the commands array to the point's coordinates.

The command array can contain the next values:

• up - it means that the point should be moved up by 1 (the y coordination should be increased by 1)
• right - it means that the point should be moved right by 1 (the x coordination should be increased by 1)
• down - it means that the point should be moved down by 1 (the y coordination should be decreased by 1)
• left - it means that the point should be moved left by 1 (the x coordination should be decreased by 1)

Pay attention: The method should return a new point, not modify the input one.

For example, the method takes the next values: Point(x: 10, y: 10) and new String[] {"up", "up", right", "down"}. So the result will be Point(x: 11, y: 11) because:

• x: 10, y: 10 the initial values.
• Apply the "up" command and the coordinates become x: 10, y: 11.
• Apply the "up" command and the coordinates become x: 10, y: 12.
• Apply the "right" command and the coordinates become x: 11, y: 12.
• Apply the "down" command and the coordinates become x: 11, y: 11.
