Stack vs. Queue Data Structures

In Data Structures, a stack and a queue are two fundamental structures used for storing and retrieving data. Here is the difference between them:

• Stack: A stack is a Last In First Out (LIFO) data structure where the last element added is the first one to be removed. It follows the principle of "Last In, First Out."
• Queue: A queue is a First In First Out (FIFO) data structure where the first element added is the first one to be removed. It follows the principle of "First In, First Out."

Scenarios for Using Stack Data Structure:

Stacks are more suitable for scenarios where you need to track the order of elements or perform operations in a Last In First Out manner. Some examples include:

• Implementing function call history in a programming language
• Undo feature in text editors or design tools
• Expression evaluation in compilers

Scenarios for Using Queue Data Structure:

Queues are more suitable for scenarios where you need to process elements in a First In First Out order. Some examples include:

• Printer spooling in operating systems
• Buffer management in networking
• Task scheduling in operating systems
