π Welcome to Part 105 of Code & Debugβs DSA in Python Course!
In this lecture, we tackle the classic Minimum Platforms problem from GFG by first understanding the Brute Force solution and then moving to a highly efficient Two-Pointer Optimized approach.
π What youβll learn in this video:
β
Problem understanding with real-life train schedule analogy
β
Brute Force approach using pairwise overlap comparison
β
Optimal approach using sorted arrival/departure arrays and two-pointer technique
β
Step-by-step dry run to visualize platform allocation
β
Time and space complexity analysis of both methods
