A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. Think of it as a stack of plates: you add a new plate on top, and when you need a plate, you take the top one off1.
Key Operations
Push: Adds an element to the top of the stack.
Pop: Removes the top element from the stack.
Peek: Returns the top element without removing it.
IsEmpty: Checks if the stack is empty.
IsFull: Checks if the stack is full (in case of fixed-size arrays)1.
Implementation in Python
Here is a simple implementation of a stack using a list in Python:
class Stack:def __init__(self):self.items = []def push(self, item):self.items.append(item)def pop(self):if not self.is_empty():return self.items.pop()return Nonedef peek(self):if not self.is_empty():return self.items[-1]return Nonedef is_empty(self):return len(self.items) == 0def size(self):return len(self.items)# Example usagestack = Stack()stack.push(1)stack.push(2)stack.push(3)print(stack.pop()) # Output: 3print(stack.peek()) # Output: 2print(stack.is_empty()) # Output: False STACK | English meaning - Cambridge Dictionary
