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 O(1) time.
Note: The time complexity of all the methods above should be O(1).
Constraints:
−104 ...
