It seems like we're at a point where we get tasks related to all kinds of things across the entire course and not specifically related to the topic of this chapter (this chapter's lessons up to this point are probably not test-able anyway). You can start to get a feeling that we're getting close to the end. The given difficulty levels for these should be ignored. The second one is rated Easy but I had a pretty rough time with it (I found a solution without a problem, but it is looking for the single fastest possible solution, and so of the many ways of solving this it will only accept that specific solution). On the other hand, the first one is rated medium but I found it pretty easy.

so many exciting exercise!🤓
