Data Structures and Algorithms The Complete Masterclass - Implementing a Min Stack

The video tutorial explains the implementation of a Min Stack class, detailing its methods such as push, pop, top, and get min. The push operation involves adding elements to both the stack and min stack, with conditions to maintain the minimum value. The pop operation removes elements while ensuring the min stack remains accurate. The top and get min methods return the last element of the stack and the minimum value, respectively. The tutorial concludes with a brief mention of the Max Stack, which will be covered in the next lecture.

What are the two main stacks that need to be initialized in the min stack implementation?

Describe the process of adding a new item to the min stack when it is not empty.

What should be done if the new value being added to the min stack is less than the current minimum?

Explain how the pop operation works in the min stack implementation.

What steps are taken when performing a push operation in the min stack?

What is the purpose of the get min operation in the min stack?

How does the min stack differ from the max stack in terms of implementation?
