      In this case we still must iterate through the array starting at 0 and ending at mid = (lo + hi) / 2. Since we are looking at the first call to find we will have that lo = 0 and hi = N which means that mid = (0 + N) / 2 = N / 2. This means that this loop will do a linear amount of work with respect to N / 2, which will be a Q(N) operation. Again in the best case arr[mid] …
