The master method - why can't it solve $T(n) = 2T(\frac{n}{2}) + \frac{n}{\log n}.$
What's the issue with the master theorem? Why is there like different concepts on different channels? What formula applies? what is "polynomial check"? when does the k method apply? There are so many questions in which some say master theorem cannot be applied but some give out the answers.
I m pretty confused right now - what to follow?
