Here are methods that you can use on the BinNode objects: If at any point in the recursion, the first tree is empty and the second tree is non-empty, or the second tree is empty and the first tree is non-empty, the trees violate structural property, and they cannot be identical. In an iterative version, we use the stack data structure similar to the implicit recursive stack. Making statements based on opinion; back them up with references or personal experience. The postorder traversal of an expression tree will result in the postfix form of the expression. Answer. }\) The first of these expressions can be broken down further into the difference of the expressions \(a*b\) and \(c/d\text{. Though the tree nodes will have values from 1 to 10 (incase of k=1) the order of the tree returned will be diffrent.
