Solution: Min Stack
Explore how to build a custom Min Stack data structure that efficiently supports push, pop, and retrieving the minimum element all in constant time. This lesson guides you through implementing this using two stacks, allowing you to maintain track of the minimum value without affecting performance. Understand the techniques to optimize stack operations for specialized use cases.
We'll cover the following...
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 ...
