A tree is a finite set of one or more nodes connected by edges such that i) There is a specially designated node called the root ii) The remaining nodes are partitioned into n (>=0) mutually exclusive disjoint sets. Basic Terminology: i) Node: Each data item in a tree is called a node. It specifies …
Singly Linked Lists: A linked list is a data structure where data can be represented as a chain of nodes. Each node of a linked list contains two parts: one is the address part, another is the data part. The address part holds the address of the node which is next to or previous to …
Stacks and Queues are the most important chapters in Data Structure. Stack & Queue : Stacks: A stacks is an abstract data type. Which declares two methods PUSH and POP.? Stacks are implemented either by an array or by a linked list. The PUSH operation allows us to insert data at the end of …
