🧠 Merge Intervals - Leetcode 56 | C++ DSA | Sorting + Merging

🔓 Welcome to *Logic Unlocked*!
In this video, we solve **Leetcode 56 – Merge Intervals** using **C++**, one of the most common Medium-level array problems asked in interviews.

🎯 Problem Statement:
Given an array of intervals where intervals[i] = [start, end], merge all overlapping intervals and return an array of the non-overlapping intervals.

📘 What You'll Learn:
✅ Brute-force logic and why it fails
✅ Optimal solution using sort + merge
✅ Dry run with visualization of overlapping intervals
✅ C++ code walkthrough step by step
✅ Time & space complexity analysis

📌 Problem Type: Arrays / Intervals / Sorting
📌 Difficulty: Medium
📌 Common in FAANG interviews and coding rounds
