        bPos += r.nextInt(100);
    }
    LongList expected = new LongList();
    // non-in place algo, supposed to be correct
    intersect(intervals, bItervals, expected);
    String expectedStr = toIntervalString(expected, 0);
    intervals.add(bItervals);
    runTestIntersectInplace(intervals, aSize * 2, expectedStr);
