I am a second year mathematics major at the University of Chicago. My mathematical interests lie primarily in Commutative Algebra and Dynamical Systems (specifically polygonal billiards). I've recently finished a paper on billiards in isosceles triangles which I hope to publish soon.

I've edited the question to fix the formatting. You can view the commands I used by right-clicking the formatted math and selecting "View math as"->"TeX commands"

comment find recursive solution $T(n)=2T(n/2)+n-1$
This is the exact same text as math.stackexchange.com/questions/394962/…, which was deleted 5 minutes ago. Presumably you are the same user, posting under a different account. I don't know why you deleted the question and reposted it, but this is generally considered misuse of the site, and you should try not to do so in the future.

This is your 5th question in 10 minutes, with no work shown. It appears you are simply typing up your homework and asking us to do it for you. That is not what this site is for, and you are unlikely to get the help you want unless you make an effort to improve your questions.
