The mini project based on Python Datastructure (Stack) the performing undo and redo operation in this mini project. Stack Concept Used: LIFO (Last In, First Out)
Undo Stack: Stores recent actions
Redo Stack: Stores undone actions
Efficient Data Handling: Undo/Redo works in O(1) time
Practical Use: Text editors, banking systems, version control, etc. Concept: Stack
A stack is a Last-In-First-Out (LIFO) data structure. Think of it like a stack of plates — the last plate you put on is the first one you take off.
Main Operations:
push(item) → Add an item on top of the stack
pop() → Remove the topmost item
Undo and Redo actions are implemented using two stacks:
undo_stack → Stores previous actions (for undo)
redo_stack → Stores undone actions (for redo)
