⁉️What is a Stack?
A stack is an abstract data type that follows the Last-In-First-Out (LIFO) principle. In a stack, elements are inserted and removed from only one end, which is known as the top of the stack.
👍Advantages of Stack:
- Easy to implement and use.
- Efficient memory management.
- Supports backtracking in algorithms and programming languages.
- Provides a simple and organized way to manage and store data.
👎Disadvantages of Stack:
- Limited functionality compared to other data structures.
- Size limitations due to finite memory.
- Can lead to stack overflow errors if too many elements are added.
📌Use Cases:
- Expression evaluation in programming languages.
- Backtracking in algorithms.
- Managing function calls and recursion in programming.
- Memory management in operating systems.
- Web browser history management.
🖊️Summary:
A stack is a Last-In-First-Out (LIFO) data structure that allows insertion and deletion of elements from only one end, known as the top of the stack. Stacks are easy to implement and use, provide efficient memory management, and are useful for backtracking in algorithms and programming languages. However, they have limited functionality compared to other data structures, size limitations due to finite memory, and can lead to stack overflow errors if too many elements are added.
