Solution: Number of Visible People in a Queue
Explore how to determine the number of people each individual can see to their right in a queue by using a monotonic decreasing stack. Understand the visibility criteria based on height comparisons and implement an efficient linear time solution that tracks visibility while traversing the queue.

Statement
You are given an array heights representing n people standing in a queue, numbered from 0 to n - 1 from left to right. Each element heights[i] denotes the height of the person at position i. All heights are distinct.
A person at position i can see a person at position j (i < j) to their right if every person between them is shorter than both heights[i] and heights[j].
