Frequently Asked Questions (FAQs) on Monotonic Stack
1. What is a monotonic stack?
A monotonic stack is a data structure that maintains either non-increasing or non-decreasing order of elements.
2. How is a monotonic stack different from a regular stack?
Unlike a regular stack, a monotonic stack ensures that the elements are in a specific order, either non-increasing or non-decreasing.
3. What are the typical use cases for a monotonic stack?
Monotonic stacks are commonly used in problems involving finding the next greater element, next smaller element, or solving various algorithmic problems efficiently.
4. Can you provide an example of solving a problem using a monotonic stack?
One common example is finding the next greater element to the right for each element in an array using a monotonic stack.
5. Are there any common pitfalls or challenges when using a monotonic stack?
A common challenge is understanding when to use a monotonic stack and ensuring that the stack’s ordering is maintained correctly throughout the algorithm.
