Linear Data Structures $($Non$-$Primitive$)$:$$

$1.$ Array:

a$)$ Explain the concept of an array. Provide an example to illustrate how arrays are used in programming.

b$)$ Write a program for array implementation.

$2.$ Linked List:

a$)$ Define a linked list and describe its basic components. Discuss the differences between singly linked lists and doubly linked lists.

b$)$ Write a program for linked list implementation.

$3.$ Stack:

a$)$ Explain the principles of a stack. Describe how a stack can be implemented using an array.

b$)$ Write a program for stack implementation.

$4.$ Queue:

a$)$ Discuss the concept of a queue. Differentiate between a circular queue and a priority queue.

b$)$ Write a program for queue implementation.

Non$-$Linear Data Structures $($Non$-$Primitive$)$:$$

$1.$ Trees:

a$)$ Explain the hierarchical structure of trees. Differentiate between a binary tree and a binary search tree.

b$)$ Write a program for binary tree implementation.

$2.$ Graphs:

a$)$ Define a graph and discuss its various representations $($adjacency matrix, adjacency list$).$

b$)$ Write a program for graph implementation.
