Step 1
  1.  

Data structure:

  • Data structure is defined as a collection of data values, operations that are performed on the data, and the relationships among the data values.
  • To represent basic values in programming language, primitive data structures are used.
  • To store multiple values in a single variable, non-primitive data structures are used.

Example for data structures:

  • Integer, char, Boolean and pointers are the examples of primitive data structures.
  • Examples of non-primitive data structures include array, stack, list, tree, and so on.
Step 2

2.

Mathematical model:

  • Mathematical model defines a container, which contains countable number of objects where the objects are connected through a binary relationship.
  • An example of mathematical model of data structure is an Abstract Data Type (ADT).
  • In mathematical model, the basic operations which can be performed on the containers include insertion, deletion, and so on.
  • A list data structure is a...
