start learning

Question		Answer
Waht is depth first traversal? start learning		proceeds along a path from the root through one child to the most distant descendant of that first child before processing the second child. Implementation uses a stack.
What is breadth first traversal? start learning		proceeds horizontally from the root to all of its children then to its children’s children and so on... Implementation uses a queue.
what are the 6 possible types of travesal? start learning		VLR, VRL, LVR, RVL, LRV, RLV
what are the 3 most common types of traversal? start learning		VLR Preorder, LVR inOrder, LRV PostOrder
Waht is preorder traversal? start learning		VLR Vist the root node then the left and finaly the right
what is inorder traversal start learning		LVR visit the lft node then the root node then the right node
what is post order traversal? start learning		LRV vist the leftnode then the right then the root
what does VLR stand for? start learning		V: Visit the node L: Traverse the Left subtree R: Traverse the Right subtree
