Rotate Image - Leetcode 48 | Matrix Rotation In-Place | C++ DSA

🔓 Welcome to Logic Unlocked! In this video, we solve Leetcode 48 – Rotate Image, a classic matrix manipulation problem where we rotate a 2D NxN matrix 90 degrees clockwise *in-place* using C++. 🎯 Problem Statement: You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees clockwise. You must rotate the image in-place, meaning you have to modify the input 2D matrix directly. 📘 What You’ll Learn: ✅ Brute-force approach (using extra matrix) ✅ Why extra space is not allowed in the final solution ✅ Optimal in-place rotation: transpose + reverse each row ✅ Step-by-step dry run and visual explanation ✅ C++ code walkthrough ✅ Time and space complexity analysis 📌 Problem Type: Matrix / Array / In-Place Algorithm 📌 Difficulty: Medium 📌 Commonly asked in interviews at Google, Amazon, Microsoft 🔗 Problem Link: https://leetcode.com/problems/rotate-... 🎥 This video is part of the Matrix Questions Playlist on Logic Unlocked — breaking down logic step-by-step for strong DSA fundamentals. 💬 Drop your doubts or approaches in the comments 👍 Like if you understood the trick 🔔 Subscribe to Logic Unlocked for clean C++ DSA explanations #leetcode48 #rotateimage #matrixrotation #cppdsa #logicunlocked #inplacealgorithm #arrayrotation #dsa #interviewprep
