Limitations of Stack in Data Structures

Limitations of Stack in Data Structures is a DSA topic. In plain words you use it for undo typing in a tiny editor. Don’t start with a slogan — start with that picture.

Smallest example: push / pop LIFO. Type it, run it, and say what you see. If you can do that from memory, you know Limitations of Stack in Data Structures.

From the example next to this theory: Limitations of Stack in Data Structures — stack is LIFO: push/pop from the same end.

Trap — pop on empty. Fix that before you talk about advanced DSA.

Viva — what is Limitations of Stack in Data Structures? Then show push / pop LIFO. Then name the trap.

Exam tip

What is Limitations of Stack in Data Structures? Show this: push / pop LIFO. Trap: pop on empty.

Example

stack = []
stack.append(10)   # push
stack.append(20)
print(stack.pop()) # 20
print(stack[-1])   # peek → 10

Limitations of Stack in Data Structures — stack is LIFO: push/pop from the same end.
