Solution: Min Stack
Explore how to implement a custom stack called Min Stack that efficiently supports push, pop, and minimum value retrieval in O(1) time. Understand the use of two stacks to maintain the current minimum and discover how this approach ensures optimal time complexity for all operations.

Statement
Design a custom stack class, Min Stack, allowing us to push, pop, and retrieve the minimum value in constant time. Implement the following methods for Min Stack:
-
Constructor: This initializes the Min Stack object.
-
Pop(): This removes and returns from the stack the value that was most recently pushed onto it.
-
Push(): This pushes the provided value onto the stack.
-
Min Number(): This returns the minimum value in the stack in ...
