When in order traversing a tree resulted e a c k f h d b g the preorder traversal would return?

Explain the three types of tree traversals with illustration?

Inorder Traversal void inorder(tree t) { if(t == NULL) return; inorder(t->left); printf("%d ", t->val); inorder(t->right); }Preorder Traversalvoid preorder(tree t) { if(t == NULL) return; printf("%d ", t->val); preorder(t->left); preorder(t->right); } Postorder Traversalvoid postorder(tree t) { if(t == NULL) return; postorder(t->left); postorder(t->right); printf("%d ", t->val);

What is the difference between traversal and search?

Traversal simply means moving from one node to the next. Generally one searches by traversing the list, comparing each node's data with a given datum, either to return a pointer to a single matching node, or to return a list of matching nodes (copied from the list being searched), or simply to collect data about the matching nodes (such as a count of all the matching nodes).

Write the algorithm for in order traversal?

Inorder(p) { If p = nil return; Inorder(p.left) process(p.data) Inorder(p.right) }

What event happened during Cleopatra's childhood?

The major event that happened during Cleopatra's childhood was her father's exile and return. This return resulted in the deaths of Cleopatra's sister and her husband (and more than likely many others as well).The major event that happened during Cleopatra's childhood was her father's exile and return.

Why didn't i get the preorder bonus from gamestop for nfs the run?

I'm afraid the only people likely to be able to answer that are Gamestop themselves. I suggest you return to the shop you purchased it from with proof-of-purchase (the receipt).

Did World War 2 play a role in the cause of the Vietnam war?

Yes. Japan's surrender during WWII, also resulted in Japan's departure from occupied territories, of which Vietnam was one. Which resulted in the return of the French, which resulted in a confrontation-which was the French Indochina War 1946-1954.

Can you trade in pre order?

If you cancel a preorder you should be able to receive a refund unless you also got something at the time of the preorder as a bonus. Trade in is never without a cost and reduction of the original purchase price and is not the same as an exchange for credit or cash where you receive you original purchase price at most retail outlets. Some carry cancellation or return charges that are also called restocking fees

If you trade in games at GAME would you get money off the New call of duty if you pre order it?

Normally you would be able to trade in toward a reduction in the price of the new preorder, but the latest expected Call of Duty release will not be not available for preorder for some months. You could get a reduced price on Call of Duty Black Ops Selling your games at a site like Glyde or Ebay would give a greater return on popular wanted games and unwanted games would not have a trade in value anyway
