You will find a MIPS assembly program BinTree.asm as downloadable code along with this assignment (it is also copied at the end of this assignment sheet). You can assemble and run this program altough until you implement the print_tree procedure it will just drop off the end of the code. The code provided will prompt the user to enter integers until a 0 is entered, terminating the input. The integers are stored in a binary tree structure using dynamic memory allocated from the heap and using the allocated variable “head” to store the memory address of the root node of the binary tree. If you encounter a value of 0 in any element representing an address, that means there are no nodes down that path of the tree (ie: if “head” is still 0 the tree is empty).

Each Node is laid out in the following format:

Item

Left Right

A node consumes 12 bytes, (i.e. 3 words). The first word contains the item value and the next two words hold pointers (addresses) to next nodes in the tree. Note: that null is represented as 0 in the nodes, and non null values are addresses in the heap space. You can inspect the heap and see the structure of the tree.

You must write the procedure print_tree which will traverse the tree in a marner to output the data values, one per line, from maximum to minimum value. This is achieved by a traversal of the right branch first, then print the item value and traverse the left branch. This procedure must be implemented using recursion and must comply with the standards as taught in class.

Each recursive call will need an activation record base on the use of the $fp register. These should be created and destroyed using the conventions set out in lecture. Following convention is important to show your understanding of activation records.

Be sure to properly document your code. If you have questions about the code please make sure you review it early and ask for clarification.

Test your solution with multiple inputs. At the very least show that the following input 44 79 12 57 75 39 66 24 21 will produce a reverse sorted output.
