At each step of the way, you must ...
$Given$:

Given an array $A$, an integer $Z$ and a value $Q$, you need to maximize the sum of $A$, by performing following operation any number of times:
We can select exactly $Z$ elements from the given array and perform XOR on each of them with $Q$.
What is the way to go about this problem? I have been...
