Course Schedule IV | DFS Solution Explained | LeetCode #1462 #codinginterviews

🚀 Leetcode Problem #1462: Course Schedule IV
In this video, we solve the Leetcode Medium problem "Course Schedule IV" using Depth First Search (DFS). This problem revolves around determining if one course is a prerequisite for another, given a list of prerequisites and queries.

📖 Problem Overview:
You're tasked with verifying direct and indirect prerequisites between courses, utilizing efficient traversal techniques for a directed acyclic graph (DAG). Learn how to construct an adjacency list and use DFS to determine paths effectively.

🧠 Topics Covered:
✅ Graph Representation (Adjacency List)
✅ Depth First Search (DFS) Algorithm
✅ Boolean Array for Results
✅ Edge Cases and Optimization

📘 Example:
Input: numCourses = 3, prerequisites = [[1,2],[1,0],[2,0]], queries = [[1,0],[1,2]]
Output: [True, True]
