# Learning Profile for Assignment #1 - Question #6 - Computer Science 272: Data Structures and Algorithms
Name: Mo Khan
Student ID: 3431709
## Problem Statement
Design and implement a MinStack data structure that can store comparable elements and supports the stack operations `push(x)`, `pop()`, and `size()`,
as well as the `min()` operation, which returns the minimum value currently stored in the data structure.
All operations should run in constant time.
## Description of the Code
## Errors and Warnings
