Not all data is created equal! In this lecture, we master the Priority Queue, one of the most powerful and frequently used data structures in the C++ Standard Template Library (STL).

While a standard queue follows "First-In, First-Out," a Priority Queue ensures that the most important element is always served first, regardless of when it joined the line. Whether you're building a pathfinding algorithm like Dijkstra’s or a CPU task scheduler, this is the tool you need.

🚀 What You’ll Learn:
The "Priority" Concept: How elements are ordered automatically (Max-Heap vs. Min-Heap).

Efficiency Breakdown: Why insertion and deletion take O(logN) and how it compares to sorting an array.
