- Designing a stack that supports push, pop, top, and retrieving the minimum element in constant time is a common problem in coding interviews and competitive programming.
- Implementing a solution for the Min Stack problem requires tracking the minimum element seen up to each layer of the stack using two stacks for efficiency.
- Building a base solution for the Min Stack problem by initializing two stacks, and optimizing the solution by removing redundancies can distinguish a good solution from a great one in interviews.
