3 (a) The following is the pseudocode for a recursive algorithm to print the values stored in a Binary Tree (in no particular order): 1 print Tree (BTNode t) 2 { if ( t != END ) { print (t.val) print Tree(t.left) print Tree (t. right) } 9 } 4 5 6 7 8 Give the pseudocode of a non-recursive algorithm to print the contents of a Binary Tree (in no particular order) with a complexity that is no worse than the above recursive algorithm. Hint: you may use a Stack Abstract Data Type in your answer. [10 marks]
