How i can use bitmasking technique to solve spoj XMAX problem, I am a beginner its hard to understand bit masking… Can anyone help me to understand bit masking well and how i can implement that in XMAX problem

That problem is extremely similar to current contest problem XORSUB, so we should probably refrain from discussing a solution to that problem.
However we can discuss the bitmasking technique in general. Read about it here and ask about any specific doubts if they arise.
I don’t think, you can solve XMAX using bitmasking, the constraints are too big for bitmasking to be useful.
Please see the following link for approach to solve the problem discrete mathematics - Maximization with xor operator - Mathematics Stack Exchange
I’m just confused how to use this technique to get sub arrays. Thanks sir…
I will try to find out the possible solution thanks sir…
glad to help
