...ay on-purpose to retrofit an asynchronous call into a very synchronous codebase that is many thousands of lines long and time doesn't currently afford the ability to make the changes to "do it right." It hurts every fiber of my being, but reality and ideals often do not mesh. I know this sucks.

how to calculate binary search complexity
...urrence relations :
T(N) = aT(N/b) + f(N)
Here, a = 1, b = 2
=> log (a base b) = 1
also, here f(N) = n^c log^k(n) //k = 0 & c = log (a base b)
So, T(N) = O(N^c log^(k+1)N) = O(log(N))
