Implement compute() method in class MyTask that extends RecursiveTask<Long>.
This task should return the sum of consecutive integers (from startPoint to finishPoint exclusively).
If the distance between startPoint and finishPoint is more than 10, we should split this task into subtasks,
otherwise we should do the work.
The results of each subtask execution should be merged into a final result and printed out.
You can test your code in main() method.
