Implement a Stack in Python Using Merge Sort
by Kal Bartalby Kal BartalIn this post, we will be discussing the implementation of a Stack data structure in Python using the Merge Sort algorithm. A Stack is a collection of elements where the two principal operations are push and pop, adding and removing elements respectively. The Stack should be able to handle the following operations: push, pop, peek, and isEmpty. In addition, the stack should also be sorted in ascending order using the Merge Sort algorithm. Understanding the problem and understanding the concept of the Stack data structure and Merge Sort will be crucial in tackling this problem and writing a working algorithm.
