Unit III
Part –A
1. What is a data structure?
A data structure is a method for organizing and storing data which would allow efficient data retrieval and usage. A data structure is a way of organizing data that considers not only the items stored, but also their relationships to each other.
2. Why do we need data structures?
x Data structures allow us to achieve an important goal: component reuse.
x Once data structure has been implemented, it can be used again and again in various applications.
3. List some common data structures.
x Stacks
x Queues
x Lists
x Trees
x Graphs
x Tables
4. How data structures are classified?
Data structures are classified into two categories based on how the data items are operated:
i. Primitive data structure
ii. Non-Primitive data structure
a. Linear data structure
b. Non-linear data structure
6. Define ADT (Abstract Data Type)
An abstract data type (ADT) is a set of operations and mathematical abstractions , which can be viewed as how the set of operations is implemented. Objects like lists, sets and graphs, along with their operation, can be viewed as abstract data types, just as integers, real numbers and Booleans.
7. Mention the features of ADT.
a. Modularity
i. Divide program into small functions
ii. Easy to debug and maintain
iii. Easy to modify
b. Reuse
i. Define some operations only once and reuse them in future
c. Easy to change the implementation
8. Define List ADT
A list is a sequence of zero or more elements of a given type. The list is represented as sequence of elements separated by comma.
A1,A2,A3…..AN Where N>0 and A is of type element.
9. What are the ways of implementing linked list?
The list can be implemented in the following ways:
i. Array implementation
ii. Linked-list implementation
iii. Cursor implementation

10. What are the types of linked lists?
There are three types
i. Singly linked list
ii. Doubly linked list
iii. Circularly linked list
