Let A be the complete solution set of `sqrt(-x^2 +8x-15)/sqrt(1-4{x}) geq0` and B be the complete solution set of `[x + [2x]] < 18`, where {x) and [x] denotes fractional part and greatest integer of x respectively. Lets denote the set `A nn B`, then find the sum of those elements of set S which are integers.
