$(6$ pts$)$ Identify the basic operations and construct a recurrence relation $C(n)$ that characterives the time complexity of the algorithm. Determine the order of growth for $C(n)$ either solving the recurrence relation or using the Master Theorem if appropriate. You may assume that $n=2^k$ for some integer $k.$
