Algorithms 101: How Python Implements a Stack Behind the Scenes
•
How Python Implements a Stack Behind the Scenes In Python, a stack is not a built-in data structure with a specific implementation. Instead, Python leverages lists, which are highly optimized, to function as stacks. The list data structure in Python provides all the necessary operations needed to implement a stack…

Algorithms 101: How to implement a queue by using two stacks
•
用栈实现队列 In this problem, we are required to implement a queue using two stacks. The queue should support all four standard operations: push, pop, peek, and empty. 在这个问题中，我们需要使用两个栈来实现一个队列。该队列应支持所有四种标准操作：push、pop、peek 和 empty。 Approach The key idea to implement a queue using two stacks is to use one stack (stack1) to handle incoming…
