What is Data Structures?

Data structures are ways of organizing and storing data in a computer's memory so that it can be accessed, modified, and manipulated efficiently. They are an essential component of computer science and are used in various areas such as software engineering, databases, and computer graphics.

There are many different types of data structures, each with their own strengths and weaknesses, and it is important to choose the appropriate data structure for a given task. Some common examples of data structures include:

• Arrays: Contiguous block of memory used to store a collection of similar items.
• Linked Lists: A chain of nodes, each containing an element and a reference to the next node.
• Stacks: A last-in, first-out (LIFO) data structure where an element added last will be the first to be removed.
• Queues: A first-in, first-out (FIFO) data structure where elements are removed in the same order as they were added.
• Trees: Hierarchical data structures that consist of nodes with a parent-child relationship.
• Graphs: mathematical structures that represent relationships between pairs of objects
• Hash tables: A data structure that stores key-value pairs where the keys are used to quickly locate the corresponding value.

Algorithms are step by step instructions to perform a specific task and use Data Structures. It can be applied to searching, sorting, manipulating, and storing data efficiently. Algorithms like breadth-first search, depth-first search, quicksort, merge sort, and many more can be used on data structures.
