Story of Data Structure

A data structure is a way to arrange data in a computer in an effective manner. For instance, In array data structure, we can store a list of items with same data type.

What is Algorithm?

A algorithm is a process or set of rules to be followed to execute any calculations or other problem-solving operations, especially by a computer.

What is Data?

Data is a set of values of qualitative or quantitative variables about one or more persons or objects.

• Atomic − Definition should define a single concept.
• Traceable − Definition should be able to be mapped to some data element.
• Accurate − Definition should be unambiguous.
• Clear and Concise − Definition should be understandable.

Data Structures divided into two parts.

• Primitive data structure
• Non-primitive data structure

Primitive Data structure

The primitive data structures are predefined types of data. The int, char, float, double, and pointer are the primitive data structures that can hold a single value.

Non-Primitive Data structure:

Non-primitive data types are not defined by the programming language, but are instead created by the programmer.

The non-primitive data structure again divided into two types:

• Linear data structure
• Non-linear data structure

In Linear Data Structure the arrangement of data in a sequential manner is known as a linear data structure. For example: Arrays, Linked list, Stacks, and Queues. In these data structures, one element is connected to only one another element in a linear format. Whereas one element is connected to the ’n’ number of elements known as a non-linear data structure. The best example is trees and graphs. In this case, the elements are arranged in a random manner.
