3. Draw the recursion tree when n=12, where n represents the length of the array, for the following recursive method: int sumSquares(int[] array, int first, int last) \{ if (first == last) return array[first] * array[first]; int mid = (first + last) /2; return sumSquares (array, first, mid) + sumsquares (array, mid +1, last); \} - Determine a formula that counts the numbers of nodes in the recursion tree. - What is the Big- for execution time? - Determine a formula that expresses the height of the tree. - What is the Big- for memory? - Write an iterative solution for this same problem and compare its efficiency with this recursive solution
