Binomial Heap

A binomial heap is a group of binomial trees. This data structure acts as a priority queue and implements the merge operation faster.

Question

Change the following traversal into a postorder traversal.
template <typename E>
void preorder (BinNode<E>* root) {
if (root == NULL) return; // Empty subtree, do not
visit (root);
preorder (root->left ());
preorder (root->right ());
// Perform desired actio
