I need the answers with explanation. Thank you.

Sample Questioms VL. Given a binary tree of integers write a routine which will accept a pointer to the tree, traverse the entire tree and return a pointer to the smallest element (the element whose info field contains the smallest integer) of the tree as well as returning the sum total of the even integers in the tree. VII. Given a Circular Singly Linked List write a segment of code that will traverse the list and retun the number of nodes that contain an even number in their info field and the number of nodes that contain an odd number in their info field. VII. Given the following recursive equations Special (a, b)- 3a+Special (a, b-1) Special (a, 0)- 4+2'a What is the value of. 1. Special(6,4) 2. Special(8,3) IX. Given a linear linked list with a pointer to the 6h node and a pointer to the last node (obviously there is also a pointer to the first node) make the 7h node in the list the last node in the list and the last node in the list the first node in the list. You may use in your code all the routines we used in class without writing them. In addition to the above questions you have some questions I gave you last Thursday
