Binary Search. We find the min and max of the numbers and then perform binary search within this range. We then check our nums array to see if there is a continuous **subarray** with at least length k that has average greater than mid. If that is the case, we know our average is at least mid, so we set our min to mid. Otherwise, we set our max to mid.
