LeetCode 539: Minimum Time Difference | Full Solution & Explanation

Hey there, fellow coders! 🚀 In this video, we'll tackle the Minimum Time Difference problem (LeetCode Problem #539). This problem requires us to find the minimum difference in minutes between any two given time points in a 24-hour format.

🎯 What You’ll Learn:

How to convert time points into minutes from midnight to handle time calculations. Efficient sorting techniques to solve the problem in O(n log n) time complexity. Dealing with the circular nature of time by calculating the difference between the first and last time points after sorting.
💡 Key Concepts Covered:

Time conversion: We’ll learn how to convert time strings like "HH:MM" into a total number of minutes from 00:00. Sorting: We’ll explore how sorting helps minimize the complexity of calculating time differences. Edge case handling: We’ll discuss special cases like duplicate time points (e.g., "00:00", "00:00") and how to handle them in the solution.
🚀 Example Walkthrough:

We’ll walk through examples such as timePoints = ["23:59", "00:00"], and explain step-by-step how to compute the minimum time difference, which in this case is 1 minute. We’ll also solve cases where there are multiple identical time points, and return the correct result of 0 minutes.
🔧 Implementation: We will implement the solution in Python, breaking down the logic for each part of the code so that it's easy to follow. You’ll also gain insights into how to optimize the solution for large inputs.
