This series of blog posts provides an overview of stacks and queues, exploring their concepts, implementations, and practical applications. The first post introduces the basic concepts and differences between stacks and queues. The second post delves into the implementation details of stacks using arrays and linked lists, along with coding examples. The third post demonstrates the use of stacks in various algorithms like evaluating postfix expressions and solving the Towers of Hanoi problem. The final post focuses on implementing queues and highlights their applications in scenarios such as breadth-first search and real-world modeling.
