Question: What is a queue?
Instructor answer: A data structure that stores elements following the first in first out principle. The main operations in a queue are enqueue and dequeue.

Student answer: A data structure in C++ where the the first element in the queue is the first element taken out of the queue.
Grade (0-5): 5

Student answer: A queue is an abstract data type that performs operations on both ends of the list and exhibits first-in first-out behavior.
Grade (0-5): 5

Student answer: First in first out.
Grade (0-5): 4.5

Student answer: A queue is an abstract data type that involves putting an element at the back of the list. Queues use the FIFO, first in first out, idea where the first element in the list is the first that comes out.
Grade (0-5): 5

Student answer: A data structure that implements first in, first out. The element that has been there the longest is the first to get served.
Grade (0-5): 5

Student answer: a data structure that inserts elements at the end of it and removes elements from the front.
Grade (0-5): 5

Student answer: A queue is a collection of elements with the characteristics of first in first out (FIFO).  The first item in is the first item out.  All additional items are added to the end of the list.
Grade (0-5): 5

Student answer: A queue is a data structure that inserts data into a FIFO configuration, that is, data input to the structure is always at it's end, and data taken is always from the beginning.
Grade (0-5): 5

Student answer: It is a particular set of entities that are put in to a certain order by the enqueue and the dequeue functions.
Grade (0-5): 3.5

Student answer: A queue is a data type that operates under a FILO (First In Last Out) method. This means that the first element inserted into the queue is the first element removed.
Grade (0-5): 4

Student answer: like a linked list except it is first in last out
Grade (0-5): 2.5

Student answer: A queue is like a stack except it follows FIFO (First in first out) .
Grade (0-5): 5

Student answer: A queue is a data structure where the first node in is the first node out.
Grade (0-5): 5

Student answer: A queue is a First in First out data structure much like a line for a movie theatre.  The first object in line is the first object to be handled or enacted upon.
Grade (0-5): 5

Student answer: its a lot like a stack, except that the first item put into the list is the first item to be taken from the list.
Grade (0-5): 5

Student answer: a first in first out list of items, like if you put 5, 4, 3, 2, and 1 in the queue it will when you dequeue items remove the items in the same order as put in, so thus it will put out, 5, 4, 3, 2, and 1 in that exact order.
Grade (0-5): 5

Student answer: A linked list with a First In, Out structure<br>dequeue at the head of the list<br>enqueue at the end of the list
Grade (0-5): 5

Student answer: a list of objects that follow the rule first in first out, essentially a linked list that goes in order of the first object in the list is the first to be taken off.
Grade (0-5): 5
Question: What is a queue?
Instructor answer: A data structure that stores elements following the first in first out principle. The main operations in a queue are enqueue and dequeue.

Student answer: A queue is an abstract data type that is based off of the priniple of first in first out. FIFO. The first item inserted into the list will the first item taken out.
Grade (0-5): 5

Student answer: It is a "first in first out" data structure.  It can be implemented with either a linked list or an array.
Grade (0-5): 5

Student answer: an ordered list that performs task in the order of first in first out. adding items to the queue places items behind the rest of them. taking items off the queue takes the one that has waited the longest.
Grade (0-5): 5

Student answer: A queue is a linear, first-in first-out data structure. Data must be accessed in the same order it was put into the queue, so only the oldest item in the queue is accessible at any time. Main functions defined are enqueue and dequeue.
Grade (0-5): 5

Student answer: Queue is a buffer, it follows the rule of First In and First out. Queue is very useful in computer science for scheduleing .
Grade (0-5): 5

Student answer: a queue is a set of elements where the first element inserted is the first element to be removed
Grade (0-5): 5

Student answer: Is a list of items where the the user only has access to the first element and each new element is added at the end.
Grade (0-5): 5

Student answer: a queue is a list of data that follows the fifo principle, an example of this would be when you get into a line at a movie theater...the first one there gets to buy a ticket first
Grade (0-5): 5

Student answer: A queue is a data structure that holds a set of objects, which has a FIFO (first in first out) priority.
Grade (0-5): 5

Student answer: like a linked list expect first in last out

Question: What is the Euler tour traversal of a tree?
Instructor answer: A walk around the tree, starting with the root, where each node is seen three times: from the left, from below, from the right.

Student answer: When you traverse a tree of any size you will visit each node three times.  Its on the order of 3n or O(n) running time.
Grade (0-5): 4

Student answer: The Euler tour traversal of a tree begins at the root and visits each node in the tree from the left, then bottom, then right sides.
Grade (0-5): 5

Student answer: Where you visit the in order according to its data value.
Grade (0-5): 3

Student answer: It is a tree that shows how it functions. It contains parents, children, siblings, ancestors and descendents. The use of tree type algorithm is also an alternative sorting algorithm.
Grade (0-5): 2

Student answer: Start from the root, circle around the _whole_ "tree", naming each node as you see it.
Grade (0-5): 4.5

Student answer: it is where you visit the parent then you vistit the children
Grade (0-5): 1.5

Student answer: To start from the root , traveling left and visiting ever child along the way till you return to the root from the right.
Grade (0-5): 4

Student answer: Traversing a tree down to it's terminal child and then all of it's siblings, then it traverses up the terminal child's parent and all of it's siblings (repeating the first step if those siblings have children) until the root node has been visited.
Grade (0-5): 4

Student answer: The Euler tour traversal of a tree the function that iteratively keeps track of the pointer on each node.

Grade (0-5): 3

Student answer: The Euler tour traverses through the tree in a rubber-band style shape.
Grade (0-5): 3.5

Student answer: The Euler tour traversal of a tree is a specific way of navigating a tree that involves following the tree starting at the very top and moving along the left side of the tree first, cupping in to visit the parents of children nodes.  It allows for each node to be visited from the left, the right and the bottom.<br><br>The Euler tour first progresses to a left child if there is one, then progresses to it's parent, then it's next child, then it's parent's parent.
Grade (0-5): 4.5

Student answer: it runs through the parents and the children in order
Grade (0-5): 3

Student answer: it starts node on the left of the root and then proceeds to visits each node in a left to right order, visits the root, and then proceeds to repeat the previous step on the right side of the tree.
Grade (0-5): 3.5

Student answer: Travel from the root to the farthest left child<br>Backup, travel the leftmost children in the right side<br>repeat until reaching the rightmost child.
Grade (0-5): 4.5
Question: What is the Euler tour traversal of a tree?
Instructor answer: A walk around the tree, starting with the root, where each node is seen three times: from the left, from below, from the right.

Student answer: has preorder, in order, and postorder of a tree.  preorder = puts the parent node in front of the child node(s).  in order = puts the parent node between the left child and right child node(s).  postorder = puts the parent node after the child node(s).
Grade (0-5): 3.5

Student answer: The Euler traveral is when you go through a tree looking for nodes to put in the order of left, root, right. Like inOrder traversal.
Grade (0-5): 4

Student answer: An Euler traversal is a traversal that begins with the root, and travels around the outside of the tree.  Each element in the tree is visited 3 times.  From the left, from the bottom and from the right.
Grade (0-5): 5

Student answer: Euler tour traversal of a tree traverses down each branch straight to one leaf then starts again at the root and repeats until all elements have been traversed.
Grade (0-5): 4

Student answer: The Euler tour visits every node in a tree, starting with the root and working around the tree counterclockwise. in-order, post-order, and pre-order traversals can be seen as variations of the Euler tour traversal.

Question: How do you delete a node from a binary search tree?
Instructor answer: Find the node, then replace it with the leftmost node from its right subtree (or the rightmost node from its left subtree).

Student answer: if root, set root to NULL<br>else if deleting right leaf, set rightPtr of parent node to NULL<br>else if deleting left leaf, set leftPtr of parent node to NULL<br>else if deleting a left or right subtree child node, set the max leaf child in the left subtree as the new child node.
Grade (0-5): 4.5

Student answer: Traverse the tree and find the node, if the node has no children, simply delete it; otherwise set the node's data equal to the data of one of its children then set the pointer for that child to NULL.
Grade (0-5): 3.5

Student answer: first attaching the elements from the node to be deleting to alternate nodes and then deleting that node.  <br><br>delete node;
Grade (0-5): 3.5

Student answer: If you delete a node from a tree, you have to link that nodes parents to the children of that node.
Grade (0-5): 3.5

Student answer: Must delete the information that the node contains (to free up memory/ "garbage collect") and also delete the pointer (in that node's "parent") that points to the node you wish to delete.
Grade (0-5): 2

Student answer: you replace the node with the largest element of its left subtree or replace it with the smallest element of the right subtree.
Grade (0-5): 5

Student answer: You traverse the tree till you find the node you are wanting to delete.  If the node has no children you delete it.  If the node has children, before you delete, you find the left-most of its children and attach it to the root then you can delete the node.
Grade (0-5): 4

Student answer: Link the to-be-deleted's left child to the to-be-deleted's parent's left child pointer.
Grade (0-5): 4.5

Student answer: The way you delete a node from a binary search tree is first you have take the root and then see the nodes that are coming from the root. And delete the nodes and set the root to NULL.
Grade (0-5): 2

Student answer: You remove the element from the tree and move the next highest element from the left into its place.
Grade (0-5): 4.5

Student answer: delete node;
Grade (0-5): 1.5

Student answer: the deletion of a node depends upon if it has children and if it is an AVL binary search tree. Assuming it is not an AVL tree, and the node being deleted has no children, you just set its pointer to null. If it has a left child or a right child exclusively, that child replaces the deleted node, if it has two children, the left most child of the right sub tree (or right most child of the left subtree)will replace it
Grade (0-5): 5

Student answer: If the node is a leaf, just set it's parent's pointer to null and delete it, if it has a single child, set the parent's pointer to the child and delete; if it has two children, set the node to one of the middle children and remove that child from its previous position as a leaf (rightmost child of the left subtree or leftmost child of the right subtree).
Grade (0-5): 5
Question: How do you delete a node from a binary search tree?
Instructor answer: Find the node, then replace it with the leftmost node from its right subtree (or the rightmost node from its left subtree).

Student answer: In a binary search tree, you must first establish a proper replacement for the node you are about to delete, usually a child from the soon to be deleted node.  Once that replacement node has been found, you simply reassign it to where the node that is going to be deleted is.  After the deleted node has been usurped, you remove the deleted node from memory so it may be used again.<br>
Grade (0-5): 4

Student answer: It all depends on where the node is located. If its a child it can just be deleted but for a node inside the tree it must be replaced with another node that works in its place.
Grade (0-5): 3.5

Student answer: if the node has no children, delete it right away, otherwise, put either the furthest right node on the left side or the furthest left node on the right side in that place and perform a the above on that node to guarantee that it's children get handled properly.
Grade (0-5): 5

Student answer: Create a temp Node<br><br>Set temp's values to the Node after head <br>or NULL in the case of only head Node in the list. <br><br>Set head equal to temp.<br>Delete temp<br>
Grade (0-5): 2

Student answer: by searching down the tree until you find the node, and replacing the link to that node with the greatest child node on the left subtree or the least child node on the right subtree.
Grade (0-5): 4.5

Student answer: Set the nodes to NULL, where that it doesn't point to anything, and the use the DELETE opertator to clear space from memory.
Grade (0-5): 1.5

Student answer: You must first traverse the tree to find the appropriate value.  Then you must make sure that the node is a leaf node.  If it is, then you can delete the pointer to that specific node.
Grade (0-5): 3

Student answer: if the node is a leaf, you set it's parent's pointer to null.<br>if the node is in the tree you must replace the node with one in the tree:<br>either the largest in the left of the tree or the smallest in the right of the tree.<br>this can be done recursively if needed.
Grade (0-5): 5

Student answer: if the node is a leaf it can simply be deallocated/deleted from memory, and its parent's reference to it changed to NULL. If the node has a single child, the pointer to it should be made to point to its child before deleting the node. Should the node have two children, the easiest solution may be to copy the node's entire subtree to a new array or tree, delete the node and all descendants, then add the elements taken from the subtree back into the main tree.
Grade (0-5): 4.5

Student answer: not answered
Grade (0-5): 0

Student answer: you cannot delete a node because that can cause a node to have more than 2 children
Grade (0-5): 1.5
Question: How do you delete a node from a binary search tree?
Instructor answer: Find the node, then replace it with the leftmost node from its right subtree (or the rightmost node from its left subtree).

Student answer: You search the tree for the node using recursion. When you find the node, you determine whether it is a leaf or a internal node. If it is a leaf, you just delete it and set the parent pointer to that node to NULL. If it is a  node, you replace the node with either of the children nodes.
Grade (0-5): 4

Student answer: to delete the node, you would have to link the children nodes that are connected to the node to be deleted to the remaining nodes of the tree in such a way that nodes on the right of the parent node are larger than the parent and nodes on the left of the parent node are smaller
Grade (0-5): 4

Student answer: if it has no children, you just delete it. if it only has one child, just replace the node with whichever child it has. if it has both children, replace it with one of its children, and send the other child down along the other side of the new node.
Grade (0-5): 4

Student answer: pointer to the child and delete it has 2 children set the node to the child and delete it. the node to th middle will then take its place
Grade (0-5): 3
Question: How many steps does it take to search a node in a binary search tree?
Instructor answer: The height of the tree.

Student answer: Log(n) where n is the number of nodes.
Grade (0-5): 5

Student answer: log(n) steps
Grade (0-5): 5

Student answer: The number of levels and the height of the tree
Grade (0-5): 5

Student answer: It is the same as the height of the tree.
Grade (0-5): 5

Student answer: Given n elements, it would take n/2 steps to find the search criteria.
Grade (0-5): 1.5

Student answer: log n
Grade (0-5): 5

Student answer: Depends on the location of the node you are looking for. If it is the root it is one step. <br>else<br>If it is smaller than the current you are on node you go to the left.  If it is larger than the current node you are on go to the right.
Grade (0-5): 2

Student answer: 2^n where n is the # of levels the binary tree has
Grade (0-5): 2

Student answer: The number of steps to search a node is the function n-1.

Student answer: log(n)
Grade (0-5): 5

Student answer: O(log n)
Grade (0-5): 5

Student answer: O( Log (n) )
Grade (0-5): 5

Student answer: If the binary search tree is constructed efficiently, best case scenario is O(log n) time.  Where n is the number of items in the tree.<br><br>If the binary search tree is constructed poorly, with for instance the root of the tree being 1, and progressing downwards and to the right its children are each more than the last: you have a one-way linear linked list.  That worse case scenario would be a full traversal at O(n) time. Where n is the number of items in the tree.
Grade (0-5): 5

Student answer: N, n being the number of nodes.
Grade (0-5): 4

Student answer: depending on the way that the tree is ordered, it could be anywhere between log(n) and N steps.
Grade (0-5): 5

Student answer: log(n)
Grade (0-5): 5

Student answer: worst case scenario = the number of levels of the tree, ie: the node at the farthest position from the root node.  best case = 1 step if its the root node.
Grade (0-5): 5

Student answer: 3 steps at most.  There are 3 cases.
Grade (0-5): 1.5

Student answer: log(n)    where n equals the total number of nodes in the tree.
Grade (0-5): 5

Student answer: the same number of steps as the number of levels or generations in the tree
Grade (0-5): 5

Student answer: to find a node in a binary search tree takes at most the same number of steps as there are levels of the tree.
