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.
