Why do you wanna understand mo's algorithm code? practice some binary search problems instead.. mo's algo is not needed at this level.
Because it's interesting! No one should need a reason to learn things.
I was just saying it is of no use to him if he is trying to do it in perspective of cp.. of course he can learn anything but he must know it will be of no use to him in cp at this stage.
You can read this. This is easy explanation.You should solve problem to understand why you will use this algorithm otherwise it will be useless to learn.
