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 ...
