The node of the tree was the first to turn yellow
Yes. The tail node's next node is the head node, while the head node's previous node is the tail node.
Given a list and a node to delete, use the following algorithm: // Are we deleting the head node? if (node == list.head) { // Yes -- assign its next node as the new head list.head = node.next } else // The node is not the head node { // Point to the head node prev = list.head // Traverse the list to locate the node that comes immediately before the one we want to delete while (prev.next != node) { prev = prev.next; } end while // Assign the node's next node to the previous node's next node prev.next = node.next; } end if // Before deleting the node, reset its next node node.next = null; // Now delete the node. delete node;
It is a keyword generally used to rename data types, using typedef you can create alias which can be used to declare the variable. e.g. typedef struct node { int info; struct node *next; }Node; now to declare variable of struct node type we can use the word Node in place of struct node
It depends on what you mean by node. In great generality, I think it's malloc you might want to use.

If the node is to be inserted in sorted order, you must traverse the list from the head node or first node to locate the insertion point. You then point the node to its next and previous nodes, either side of the insertion point. Then update those nodes to point at the new node.That is, assuming node is to be inserted between prev and next, you would use the following algorithm (assuming every node has next and prev members):node.next = next;node.prev = prev;next.prev = node;prev.next = node;

_node* search (_node* head, _key key) { _node* node; for (node=head; node != NULL;;) { if (key == node->key) return node; else if (key < node.>key) node = node->left; else node = node->right; } return node; }
A list is data type which implements a linear data sequence container object with elements that are allocated non-contiguously. To navigate a list, we use a node class. A node refers to an element but also refers to the next and previous nodes in the sequence. A simple node may be defined as follows: template<typename T> struct node { T* data; // link to an element (of some type T) node* next; // link to next node node* prev; // link to previous node };
for (node=head; node!=null; node=node->next) printnode(node);
Refer to http://cslibrary.stanford.edu/110/BinaryTrees.html void mirror(struct node* node) { if (node==NULL) { return; } else { struct node* temp; // do the subtrees mirror(node->left); mirror(node->right); // swap the pointers in this node temp = node->left; node->left = node->right; node->right = temp; } }
No. A leaf node is a node that has no child nodes. A null node is a node pointer that points to the null address (address zero). Since a leaf node has no children, its child nodes are null nodes.
