Construct List Using XOR Queries | GeeksforGeeks POTD Solution | Efficient XOR Trick Explained 🔥

🚀 GeeksforGeeks Problem of the Day (POTD) Problem: Construct List Using XOR Queries In this video, we solve the GeeksforGeeks POTD problem "Construct List Using XOR Queries" using an optimized approach that avoids applying XOR to every element repeatedly. ✅ Understand the XOR observation ✅ Learn the lazy XOR technique ✅ Step-by-step dry run ✅ C++ solution explained ✅ Time Complexity Analysis Problem Difficulty: Medium Accuracy: 50.86% Submissions: 39K+ Approach: Instead of updating the entire array for every XOR query, we maintain a cumulative XOR value. When inserting a new element, we store it after adjusting with the current XOR. Finally, we apply the accumulated XOR once and sort the result. Time Complexity: O((N + Q) log N) Space Complexity: O(N) If this explanation helped, don't forget to Like 👍, Share 📢 and Subscribe 🔔 for daily GeeksforGeeks POTD solutions and coding interview preparation content. #GeeksforGeeks #GFGPOTD #ConstructListUsingXORQueries #CodingInterview #DSA #Cplusplus #CompetitiveProgramming #Programming
