Linear data structures: stacks

In this video the concept of stacks as a data structure is explained. Stacks follow the LIFO (Last In First Out) strategy, where the last element added becomes the top and the first to be removed. This data structure has four main operations: pushing an element onto the stack, popping an element from the stack, checking the top element, and checking if the stack is empty. An implementation of a stack using a list is provided, demonstrating how these operations work together to manage elements in the stack.
