Solution: Min Stack
Understand how to implement a Min Stack that allows pushing, popping, and fetching the minimum element in constant time. Explore the use of two stacks—main and min stack—to efficiently track minimum values while maintaining O(1) time complexity for all operations.

Statement
Design a custom stack, Min Stack, allowing us to push, pop, and retrieve the minimum value in constant time. Implement the following methods for Min Stack struct:
-
NewMinStack(): 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 ...
