I found a clean and easy-to-understand code on LeaderBoard, from userpedrosorio View Code A more important lesson learnt: visualize the procdure in your mind, and you will probably close to the smart solution!
Tony's Log HackerRank "Maximizing XOR" A natural thought is brutal-force. But as you may have already thought of, there must be a smarter one. And yes there is. Think like this: XOR gives you all different bits, if you could imagine the binary representation of L^R, it can be ...

HackerRank - "Xor subsequence" The Editorial provides a Fast Fourier Transformation solution O(nlgn)... which is too maths for me. In the leaderboard, I found a not-that-fast O(n^2) solution, with a very smart observation. #include <cstdio>#include<cstring>#include<iostream>#include<...
