Post # 9 Assignment #2

Hello everyone! To begin with, let me aplogize for my absence.  I want to share my thoughts about assignment #2. Well, I have to say that question #1 had been bugging me for some time. Since I was kind of sure that I had to use induction, the problem that did not fit in any of induction types, gave me some headache. However, later it turned out that we had to provide only logical proof for the problem. Other problems in assignment were in some ways similar to stuff we did in class, so solving them was not a big deal.
