Postorder traversal of a binary tree
struct NODE
{
struct NODE *left;
int value; /* can take any data type */
struct NODE *right;
};
postorder(struct NODE *curr)
if(curr->left != NULL) postorder(curr->left);
if(curr->right != NULL) postorder(curr->right);
printf("%d", curr->value);
}
In a preorder traversal, first (pre) the root is visited and then the left & right sub- trees are traversed. In a postorder traversal, first the left sub-tree is visited, followed by right sub-tree which is then followed through root. In inorder traversal, first the left sub- tree is visited, followed by root, followed by right sub-tree.
List areutilized to maintainPOLYNOMIALS in the memory. For example, we have a functionf(x)= 7x 5 + 9x 4 - 6x³ + 3x². Figure depicts the representation of a Polynomial by means o

What are expression trees? The leaves of an expression tree are operands, like as constants or variable names, and the other nodes have operators. This certain tree happens to

One can change a binary tree into its mirror image by traversing it in Postorder is the only proecess whcih can convert binary tree into its mirror image.
QUESTION (a) Construct a binary tree for the following numbers assuming that a number greater than the node (starting from the root) goes to the left else it goes to the right.
