The correct solution for the second one, Bug Fix, does not produce the desired output indicated in the commented section. The order of several outputs are different. Because of the fact that the task begins with TreeMap, I assumed that the order of outputs mattered. I ended up wasting a lot of time trying find a solution that would output in the order it said it wanted, finally gave up and looked at the solution, only to find that it was something I had already tried, and the task passed even though the output is wrong.
