I need the ans of 4 part other 3 parts ans are posted here i needed ans of part 4 

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.
