Tree is dynamic data structures. Trees can expand & contract as the program executes and are implemented via pointers. A tree deallocates memory whereas an element is deleted.
Non-linear data structures: Linear data structures contain properties of ordering relationship (can the elements/nodes of tree be sorted?). There is no first or last node. There is no ordering relationship amongst elements of tree.
Items of a tree can be ordered partially into a hierarchy through parent-child relationship. Root node is at the top of the hierarchy & leafs are at the bottom layer of the hierarchy. Therefore, trees can be termed as hierarchical data structures.
A shop sells books, maps and magazines. Every item is identified by a unique 4 - digit code. All books have a code starting with a 1, all maps have a code which starts with a 2 and
The simplest implementation of the Dijkstra's algorithm stores vertices of set Q into an ordinary linked list or array, and operation Extract-Min(Q) is just a linear search through
B-trees are special m-ary balanced trees utilized in databases since their structure allows records to be added, deleted & retrieved with guaranteed worst case performance. A B-
Since the stack is list of elements, the queue is also a list of elements. The stack & the queue differ just in the position where the elements may be added or deleted. Similar to
