What are the three points of view in Kolmogorov Complexity?


I was reviewing for my finals and find this question that I have totally no clue.

Compare the following to statements from three points of view:

  1. There exists a constant $ c > 0$ such that for all palindromes $ x \in \{0, 1\}^*$ we have $ K(x) \leq \lfloor x / 2 \rfloor + c$ .

  2. There exists a constant $ c > 0$ such that for all $ x \in \{0, 1\}^*$ we have $ K(\overline{x}) \leq K(x) + c$ where $ \overline{x}$ is the complement of $ x$ .

So what are the three points of view am I suppose to use and where should I start?
