What is a Monotonic Stack?
A Monotonic Stack is a stack whose elements are monotonically increasing or decreasing. It contains all qualities that a typical stack has and its elements are all monotonically decreasing or increasing.
Some features of a monotonic stack:
- It is a range of queries in an array of situation
- The minima/maxima elements
- When an element is popped from the monotonic stack, it will never be utilized again.
How to Identify and Solve Monotonic Stack Problems ?
We all know what is Stack and how it works so today we will learn about a special type of data structure called monotonic stack. Problems using monotonic stack are difficult to identify if you do not know its concept. So in this post, we are going to discuss some key points that will help us to identify these problems.
But Before that let’s discuss the monotonic stack and its features.
