In order\n   to test more aspects of your code, write your own unit tests.\n - Take another very careful look at the assignment description. Try to find out if you\n   misunderstood parts of it. While reading through the assignment, write more tests.\n\nBelow you can find a short feedback for every individual test that failed.\n\n======== LOG OF FAILED TESTS ========\nYour solution achieved a testing score of 0 out of 150.\n\nBelow you can see a short feedback for every test that failed,\nindicating the reason for the test failure and how many points\nyou lost for each individual test.\n\nTests that were aborted took too long too complete or crashed the\nJVM. Such crashes can arise due to infinite non-terminitaing\nloops or recursion (StackOverflowException) or excessive mamory\nconsumption (OutOfMemoryException).\n\n[Test Description] downsweep should correctly handle trees with a single leaf\n[Observed Error] an implementation is missing\n[exception was thrown] detailed error message in debug output section below\n[Lost Points] 1\n\n[Test Description] lineOfSight should correctly handle an array of size 5\n[Observed Error] an implementation is missing\n[exception was thrown] detailed error message in debug output section below\n[Lost Points] 1\n\n[Test Description] parLineOfSight should invoke the parallel construct 30 times (15 times during upsweep and 15 times during downsweep) for an array of size 17, with threshold 1\n[Observed Error] an implementation is missing\n[exception was thrown] detailed error message in debug output section below\n[Lost Points] 3\n\n[Test Description] downsweepSequential should correctly handle empty chunks.
