Solution: Number of Visible People in a Queue
Explore how to calculate the number of people visible to each individual in a queue by applying a monotonic decreasing stack approach. This lesson teaches you to implement an efficient O(n) algorithm in C++ that tracks visibility based on height comparisons, helping you master stack applications for coding interviews.

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].
