Maximize Number of Courses | Greedy + Heap Approach in C++ | Leetcode Hard Explained
In this video, we solve a Leetcode hard-level problem: **"Course Schedule III"** using a Greedy + Max Heap approach in C++.
Learn how to take the maximum number of courses while respecting their duration and deadlines.
We use priority\_queue and sorting to build an efficient O(n log n) solution.
🔸 Topics Covered:
* Course scheduling strategy
* Sorting by deadline
* Using max-heap to manage course durations
* Replacing longer courses with shorter ones when needed
✅ **Input Example:**
```cpp
courses = {{100,200}, {200,1300}, {1000,1250}, {2000,3200}};
```
✅ **Output:** `3`
This C++ solution is clean, fast, and perfect for coding interviews and competitive programming.
